Vocabulary Matching quiz 4 Limiting factors Mutualism Non-native species Immigration Organism Species Parasitism Photosynthesis Population Emigration Respiration

______A. A group of similar looking organisms that breed together and produce fertile offspring.

______B. An organism which is not normally found in an area and may have no natural predators which allows it to expand its population.

______C. An individual living thing like a microbe, fungi, plant, or animal

______D. Movement away from an area

______E. A symbiotic relationship in which both species benefits

______F. The process in which an organism converts sunlight energy, water and carbon dioxide into glucose and oxygen gas.

______G. Movement into an area

______H. The process in which an organism converts glucose and oxygen into ATP, water and carbon dioxide. d.

______I. A group of organisms of the same species that live in the same area at the same time.

A small, cold creek flows through a dense forest. The trees that line the banks of the creek provide shade for most of the day. Algae grow well only in the few areas of the creek that receive direct sunlight for several hours each day. Most of the food energy enters the creek ecosystem in the form of dead leaves that fall from the trees. According to the food web, which of these best describes the role of the dead organic matter? A carnivore B herbivore C omnivore D producer

According to the food web, which of these is a predator?

A Brown Stonefly B Black Stonefly C Caddis Fly D Mayfly A fire swept through the forest, burning all the leaves but leaving the trees standing. This greatly increased the amount of direct sunlight reaching the creek, but did not produce more than the usual amount of erosion. As a result of the fire, which of these most likely increased in the creek? A organic matter B Brown Stoneflies C Caddis Flies D Algae
