1) AUTOTROPHIC -

Organisms that perform autotrophic nutrition are commonly referred to as:

a) ______or

b) ______

What makes autotrophic nutrition different from heterotrophic nutrition?

Autotrophs/producers have the ability to ______and store solar (light) energy from the sun in the form of energy rich compounds. In other words, ______nutrients from ______substances in their environment.

Autotrophs have the ability to use an inorganic atmospheric gas (CO2) to produce organic nutrients, such as carbohydrates and proteins.

Examples of producers performing autotrophic nutrition are: -An ______tree making its own food…

-A ______plant using CO2 and ______to ______C6H12O6.

______, an ______plant, using the______

CO2 in a lake to produce food for itself.

-A corn growing and using ______energy and CO2 to produce its own food.

When Producers perform autotrophic nutrition, they ______

______CO2,

Because they use the CO2 as a

______to synthesize GLUCOSE!

! #! 2) ______NUTRITION- Organisms that perform heterotrophic nutrition are commonly referred to as:

______or

______A OBTAINS nutrients from ones environment……..they consume ______organic molecules!! • There are many different ______of . Most heterotrophs perform the following 3 processes a) INGESTION- ______b) - organic compounds such as proteins and starches are too ______to pass through most cells, therefore digestion ______these organic molecules so they can ______cells and organelles. c) ELIMINATION or EGESTION- ______

Examples and/or types of Heterotrophs: a) Rare, but some ______are considered heterotrophic because they consume organic molecules by stealing them from a HOST (dodder, which is a creeping vine is an example)

b) ______= obtaining nutrients from its environment, such as digesting a dead log

c) ______changing organic material into simple nutrients (decomposing) d) A ______INGESTS a daphnia, then DIGESTS it….and later EGESTS some materials….All of these events are closely associated with the life process known as ______nutrition. e) ______- Amoebas and white blood cells perform a type of INGESTION known as phagocytosis. Food is digested INTRACELLULAR! f) A ______tapeworm feeding in the body of a dog.

! %! ! An important characteristic to observe when classifying organisms is whether the organism is a producer or . Living things are classified as producers or consumers according to:

______.

-Besides the obvious difference between producers & consumers…there are also many different types of Consumers who ______their food from different sources in different ways! Some different types of consumers/heterotrophs are:

**Now APPLY your understanding of the definitions by labeling each of the following organisms as either an or a heterotroph.

**Briefly define the words below: (HINT: They are synonyms for autotroph & heterotroph, so you can refer back to page 1)

Producer- ______

Consumer- ______

**Next, APPLY your understanding of the terms producer/consumer by labeling each of the following organisms as either a producer or a consumer.

Name ______# ___ Core-Curriculum…NUTRITIONAL RELATIONSHIPS

host , autotrophic , compete , nonliving, Relationships, consumers, interact, positive, predator/prey, environments, interdependence

The components of living systems, from a single cell to an , ______to maintain balance.

Food chains and food webs identify the relationships among producers, ______, and carrying out either ______or heterotrophic nutrition.

***______between organisms may be negative, neutral, or______. Some organisms may interact with one another in several ways. They may be in a producer/consumer, ______, or parasite/______relationship; or one organism may cause disease in, scavenge, or decompose another.

-An ecosystem is shaped by the ______environment as well as its interacting species. -The world contains a wide diversity of physical conditions, which creates a variety of______.

-In all environments, organisms ______for vital resources..

The ______of organisms in an established ecosystem often results in stability over hundreds and thousands of years. For example, as one population increases, it is held in check by one or more environmental factors or another species.

**The energy for life comes primarily from the______. * provides a vital connection between the Sun and the ______needs of living systems.

-Plant cells and some one-celled organisms contain ______the site of photosynthesis. The process of photosynthesis uses solar energy to combine the ______molecules carbon- dioxide and water into energy-rich organic compounds (glucose) and release ______to the environment.

-In all organisms, organic compounds can be used to ______other molecules such as proteins, DNA, starch, and fats.

The chemical energy stored in ______can be used as a source of energy for life processes.

*In all organisms, the energy stored in organic molecules may be ______during cellular respiration.

**This energy is temporarily ______molecules. In many organisms, the process of cellular respiration is performed in ______, in which ATP is produced more efficiently, oxygen is used, and carbon dioxide and water are released as wastes.
