Ecology Review Questions 2 The 1, Which title would be most appropriate for a textbook on general ecology? (1.) Interactions Between Organisms and Their Environment (2.) The Cell and its Organelles (3.) The Hereditary Mechanism of Drosophila (4.) The Physical and Chemical Properties of Water 2. The following chart lists four groups of factors relating to an ecosystem. Which group contains only abiotic Group A Group D Group C Group D Swthght Sunlbght SwillghI Sun1Qbt Gr€enØants Oflma Goenpants Rainfall Ral Raiafl QonwnQr Minotats Poduuera CxyQer. Gases Carbon lio Water factors? (1.) group A (2.) group B (3.) group C (4.) group D 3. The most likely result of a group of squirrels relying on limited resources would be (1.) competition between the squirrels (2.) an increase in the number of squirrels (3.) increased habitats for the squirrels (4.) a greater diversity of food for the squirrels 4. An ecosystem is represented in the illustration below. This ecosystem will be self-sustaining if (1.) the organisms labeled A outnumber the organisms labeled B (2.) the type of organisms represented by B are eliminated (3.) the organisms labeled A are equal in number to the organisms labeled B (4.) materials cycle between the organisms labeled A and the organisms labeled B in 5. A certain plant requires moisture, oxygen, carbon dioxide, light, and minerals order to survive. This statement shows that a living organism depends on (1.) abiotic factors (2.) biotic factors (3.) carnivore-herbivore relationships (4.) symbiotic relationships 6. Although three different bird species all inhabit the same type of tree in an area, competition between the birds rarely occurs, The most likely explanation for this lack of competition is that these birds (1.) are unable to interbreed (2.) have a limited supply of food (3.) share food with each other (4.) have different ecological niches 7. An abiotic component of the biosphere is represented by the (1.) mushrooms in a cave in the Catskill Mountains (2.) population of deer in a forest at the close of the hunting season (3.) annual range of temperatures in a lake in New York State (4.) interactions of insect species in a cornfield 8. Termites can be found living in dead trees partially buried under soil and stones. Within the tree trunks, the termites feed on the wood fiber, creating passageways having a high humidity. Protozoans living within the digestive tract of the termite digest the wood fiber. What are the biotic factors in this habitat? (1.) soil and humidity (2.) humidity, soil, and stones (3.) termites and protozoans (4.) tree trunk, stones, and protozoans 9. Some crows, vultures, and other birds that feed off dead animals are classified as (1.) saprophytes (2.) herbivores (3.) scavengers (4.) producers 10. The diagram represents the feeding areas during summer and fall of two populations in the same ecosystem. Both populations feed on oak trees. The portion of the diagram labeled X most likely indicates that SUMMER FALL (I.) these populations compete for food in the fall, but not in the summer (2.) the species are separated by a geographic barrier in the fall (3.) the supply of oxygen is greater in the summer than in the fall (4.) random mating occurs between these species in the summer 11. The chart represents the characteristics necessary for the maintenance of a self- sustaining ecosystem. Which does letter X most wmcP,cLc likely Wi*tG represent? (1.) Few Biotic Factors (2.) Symbiotic Relationships (3.) Lack of Abiotic Factors (4.) A Cycling of Materials 12. If two different bird species in the same habitat require the same type of nesting site, both species will most likely (i.) compete for the nesting sites (2.) interbreed and share nesting sites (3.) use the nest of other bird species (4.) change their nesting site requirements 13. A student set up a terrarium containing moist soil, several plants, and snails. The terrarium was placed in a sunny area. Which factor is not essential for the maintenance of the terrarium? (1.) a cycling of materials between organisms and their environment (2.) a constant source of energy (3.) a living system capable of incorporating energy into organic compounds (4.) the introduction of another heterotroph into the terrarium 14. A student measured some abiotic factors present in an aquarium in a biology laboratory. Which data did the student most likely record? (1.) the weight and color of each type of scavenger (2.) the temperature and oxygen content of the water (3.) the size and number of each species of fish (4.) the number of each type of green plant and each type of snail 15. An ecosystem jji considered to be self sustaining if (1,) it lacks a constant supply of energy (2.) cycling of materials occurs between organisms and their environment (3.) there is interaction between biotic and abiotic factors (4.) some of its living systems incorporate energy into organic compounds 16. The diagram shows organisms in and around a pond. Which ecological term refers to all the organisms shown in the diagram? (1.) heterotroph (2.) community (3.) population (4.) biosphere 17. An aquarium ecosystem is shown in the accompanying diagram. A community in this aquarium consists of the (1.) fish, water, and snails (2.) plants and gravel (3.) water and gravel (4.) fish, plants, and snails 18. All of Earth’s water, land, and atmosphere within which life exists is known as (1.) community (2.) ecosystem (3.) population (4.) biosphere 19, Which group represents a population? (1.) all the vertebrates living in New York State (2.) all the flowering plants found in New York State (3.) all the plant and animal species found in New York State (4.) all the Homo sapiens living in New York State 20. An example of a population is all the (1.) field mice living in a barn (2.) field mice and owls living in a barn (3.) animals in a barn and their food (4.) animals in the barn and their surroundings 21. Which is an example of an ecosystem? (1.) a population of monarch butterflies (2.) all the mammals that live in the Atlantic Ocean (3.) all the abiotic factors found in a field (4.) the interdependent biotic and abiotic components of a pond 22. A pond community is represented in the diagram. Which term includes the interactions between the organisms of this community and the physical factors of their environment? (1.) population (2.) ecosystem (3.) biotic (4.) competition 23. A moss-covered log is overturned by a hungry bear looking for insects to eat. The bear disturbs an ant colony, and some chipmunks leave the hollow log to search for another home in the forest. Which relationship do these organisms have with each other? (1.) They are all of the same species. (2.) They all require the same type of food. (3.) They are part of a community. (4.) They are abiotic factors in a forest..

Kamloops, BC: Author. © Grasslands Conservation Council of BC 2 Grassland Ecosystems Ecological systems (ecosystems) consist of all the living organisms in an area and their physical environment (soil, water, air). Ecosystems are influenced over time by the local climate, the parent material under the plants, variations in the local landscape, disturbances such as fire and floods, and by the organisms that live in them. Grassland ecosystems in British Columbia generally occur in areas where the climate is hot and dry in summer and cool to cold and dry in winter. The parent material is often composed of fine sediments, and grasslands are most often in valley or plateau landscapes. The organisms that live in them include plants and animals that have adapted to the dry climatic conditions in a variety of ways. Differences in elevation, climate, soils, aspect, and their position in relation to mountain ranges have resulted in many variations in the grassland ecosystems of British Columbia. The mosaics of ecosystems found in our grasslands, including wetlands, riparian areas, aspen stands and rocky cliffs, allow for a rich diversity of species.

  • Ecosystems and Biodiversity
    Unit 2: Ecosystem An organism is always in the state of perfect balance with the environment. The environment literally means the surroundings. The environment refers to the things and conditions around the organisms which directly or indirectly influence the life and development of the organisms and their populations. “Ecosystem is a complex in which habitat, plants and animals are considered as one interesting unit, the materials and energy of one passing in and out of the others” – Woodbury. Organisms and environment are two non-separable factors. Organisms interact with each other and also with the physical conditions that are present in their habitats. ―The organisms and the physical features of the habitat form an ecological complex or more briefly an ecosystem.‖ (Clarke, 1954). The concept of ecosystem was first put forth by A.G. Tansley (1935). Ecosystem is the major ecological unit. It has both structure and functions. The structure is related to species diversity. The more complex is the structure the greater is the diversity of the species in the ecosystem. The functions of ecosystem are related to the flow of energy and cycling of materials through structural components of the ecosystem. According to Woodbury (1954), ecosystem is a complex in which habitat, plants and animals are considered as one interesting unit, the materials and energy of one passing in and out of the others. According to E.P. Odum, the ecosystem is the basic functional unit of organisms and their environment interacting with each other and with their own components. An ecosystem may be conceived and studied in the habitats of various sizes, e.g., one square metre of grassland, a pool, a large lake, a large tract of forest, balanced aquarium, a certain area of river and ocean.

  • Ecology Intro
    www.logannature.org 2969 East Highway 89 P.O. Box 4204 Logan, UT 84323 Phone: 435.755.3239 Introduction to Ecology Objectives Students will understand the difference between an individual, a population, a community, and an ecosystem. Method Students will use shapes to depict individuals. They will start the activity as individuals and progress towards becoming an ecosystem. Materials At least 8-10 different shapes (multiple pieces of each shape should be cut out of paper or other material), paper and pencils for each student, a ball of yarn. Background Ecology is the study of ecosystems. But first, we have to understand what an ecosystem is. An ecosystem is a community of living organisms interacting with their abiotic environment. To best explain this to students, it is important that they understand the components you must have to make an ecosystem. The first is the individual. An individual is a single member of a species; a population is many members of the same species living in a specific habitat; a community is a group of interdependent organisms of different species growing or living together in a specified habitat. This brings us to the ecosystem where the community of living organisms interacts with the non-living components of the environment. Procedure 1. Each student will receive a single shape. This shape represents an individual of a species. 2. Each student must find at least 9 more individuals of the same species (They can find these shapes in buckets around the room). This creates a population. 3. Each student should find two more students with different species and combine their shapes to create a community of organisms.

  • Abiotic Components of a Freshwater System
    Abiotic Components of a Freshwater System Grade Level: Elementary, Middle School, High School Ecological Concepts: Abiotic, Physical factors Arizona Science Standards: Science as Inquiry; Life Science Materials: 1) Pond, stream, or aquarium 2) Loupe or magnifying lenses * 3) Chemical tests * a) pH b) Dissolved oxygen (DO) c) Phosphate d) Nitrogen 4) Rulers 5) Air and water thermometers in °C * 6) Record keeping materials 7) Sampling cups * 8) Wear boots, aqua shoes or old sneakers * May be borrowed from SCENE. BACKGROUND Water is a necessity for all life on this planet. Aquatic ecosystems can be ponds, streams, lakes or oceans. Freshwater ecosystems are usually divided into still water (ponds) and flowing water (streams). Some systems encompass both still and flowing water, such as a stream with deep pools. A variety of organisms live in freshwater, some throughout their lives, others only for certain stages, usually as immatures, or juveniles. Even in the Sonoran Desert there is naturally occurring freshwater. There are rivers and streams that flow all year long, and others, called "ephemeral," flow only during wet seasons. Ponds and pools exist as well, usually ephemerally. In functioning aquatic systems there is a variety of plant and animal life, the biotic part of the system. The abiotic component of freshwater systems is as important as the biotic. Water temperature, pH, phosphate and nitrogen levels, dissolved oxygen, and substrate composition are some of the abiotic factors to consider and measure. These must be within certain ranges for the system to be habitable for living organisms. GUIDED INQUIRY Observation/Exploration Period: Have students observe the water habitat using their eyes, magnifying lenses, dip nets, etc.

  • Environment Is Constituted by the Interacting Systems of Physical
    Elements of Environment: Environment is constituted by the interacting systems of physical, biological and cultural elements inter- related in various ways, individually as well as collectively. These elements may be explained as under: (1) Physical elements Physical elements are as space, landforms, water bodies, climate soils, rocks and minerals. They determine the variable character of the human habitat, its opportunities as well as limitations. (2) Biological elements Biological elements such as plants, animals, microorganisms and men constitute the biosphere. (3) Cultural elements Cultural elements such as economic, social and political elements are essentially manmade features, which make cultural milieu. According to Kurt Lewin, environment is of three types which influence the personality of an individual as under: (a) Physical Environment, (b) Social and Cultural Environment, and (c) Psychological Environment. These may be explained as under: 1. Physical Environment: Physical environment refers to geographical climate and weather or physical conditions wherein and individual lives. The human races are greatly influenced by the climate. Some examples are as under: (a) In the cold countries i.e. European countries the people are of white colour. Likewise, in Asian and African countries, that is, in hot countries people are of dark complexion. (b) The physique of an individual depends on climate conditions as the individual tries to adjust in his physical environment. (c) The human working efficiency also depends on the climatic conditions. 2. Social Environment: Social Environment includes an individual’s social, economic and political condition wherein he lives. The moral, cultural and emotional forces influence the life and nature of individual behaviour.

  • Concept of an Ecosystem
    CONCEPT OF AN ECO SYSTEM Dr.R.Priscilla, HoD of Physics, ADM. College for Women, Nagapattinam. Eco System The various communities of living organisms interact among themselves As well as with their physical environment like soil, air and water. This functional unit or ‘system’ made up of living and non-living components is called an ‘ecosystem’. This term ‘ecosystem’ was coined by Tansley in 1935. The interaction is through energy flow and cycling of materials. *This makes the ecosystem to sustain life continuously. *An eco system may be of any size. i.e, the whole world may be considered as an ecosystem called biosphere. *They are natural but some man made and none of the eco system is independent but all of them are interdependent. Structure and function of an ecosystem Two major components 1. The abiotic component which includes the physical environment. 2. The biotic component comprising of all the living organisms. ABIOTIC COMPONENTS BIOTIC COMPONENTS Sunlight Primary producers Temperature Herbivores Precipitation Carnivores Water or moisture Omnivores Soil or water chemistry (e.g., P, NH4+) Detritivores etc. etc. Abiotic component consists of 1. the solid mineral matter of the earth(lithosphere) 2. the water in the oceans, lakes, rivers and ice caps etc.(hydrosphere). 3.the gaseous mixture in the air(atmosphere) and 4. the radiant solar energy. The environment created and maintained by the interactions of the common environmental factors, function as a whole unit. Any of these factors cannot be removed or altered without affecting the other factors. Therefore, the environment is called HOLISTIC. Producers, consumers and decomposers Biotic Component – the organisms of ecosystems are divided into two classes.

  • Q.1 Explain Biotic and Abiotic Components of Ecosystem Along with Its Main Principles
    Government Women Polytechnic College, Bikaner Model Answers Subject-EVS (II year) CD/TD-202 Q.1 Explain biotic and abiotic components of ecosystem along with its main principles. Answer: The biotic and abiotic components of ecosystem are as follows: The abiotic components of ecosystem refer to the physical environment and its several interacting variables which can be divided into four folds: (i) Lithosphere which means the solid mineral matter on the earth and the land form. (ii) Hydrosphere, i.e. the water in oceans, lakes, river, ice-caps, etc. (iii) Atmosphere, the gaseous mixture in the air. (iv) The radiant solar energy. The energy interacts with rocks, water and gases to produce a complex environment with a large number of identifiable variables such as heat, light, rain, wind, snow, fog, dust, storm, fire. The biotic factors are divided into two categories, (i) Autotrophs (ii) Heterotrophs. The autotrophs can produce their own food. They are the green plants with chlorophyll and certain types of bacteria—chemosynthetic and photosynthetic. The heterotrophs depend directly or indirectly on the autotrophs for their food. The main principles of ecology are 1. Liebig’s law of minimum: This concept was originally applied to plant or crop growth, where it was found that increasing the amount of plentiful nutrients did not increase plant growth. Only by increasing the amount of the limiting nutrient was the growth of a plant or crop improved. 2. Shelford’s law of tolerance: It states that an organism's success is based on a complex set of conditions and that each organism has a certain minimum, maximum, and optimum environmental factor or combination of factors that determine success.
