Ecology Test Part 1 Review

Abiotic factor

• Nonliving factor inside an ecosystem

• A community of organisms where there are several interrelated food chains

• Amount of energy transferred from one trophic level to the next

• Ultimate energy source for all living organisms

Ecosystem

• Amount of energy transferred from one trophic level to the next

• A collection of different communities as well as abiotic factors

• A community of organisms where there are several interrelated food chains

• organism that feeds on plant and animal remains and other dead matter

Ecology

• Scientific study of interactions among organisms and between organisms and their environment

• Nonliving factor inside an ecosystem

• Largely feeds on carnivores or secondary consumers

• A series of steps in which organisms transfer energy by eating and being eaten

Tertiary Consumer

• organism that feeds on plant and animal remains and other dead matter

• A process by which nutrients, particularly phosphorus and nitrogen, become highly concentrated in a body of water, leading to increased growth of organisms such as algae or cyanobacteria.

• Rain containing acids that form in the atmosphere when industrial gas emissions (especially sulfur dioxide and nitrogen oxides) combine with water.

• Largely feeds on carnivores or secondary consumers.

Decomposer

• A series of steps in which organisms transfer energy by eating and being eaten

• Organisms that make their own food (autotrophs).

• Breaks down dead organic matter

• Organism that is able to make its own food

Detritivore

• organism that feeds on plant and animal remains and other dead matter

• A collection of different communities as well as abiotic factors

• A process by which nutrients, particularly phosphorus and nitrogen, become highly concentrated in a body of water, leading to increased growth of organisms such as algae or cyanobacteria.

• a change in global or regional climate patterns

• Describes living factors in the environment.

• Amount of energy transferred from one trophic level to the next

• Organisms that make their own food (autotrophs).

• A community of organisms where there are several interrelated food chains

Organism

• An individual living thing

• Breaks down dead organic matter

• Organism that is able to make its own food

• Organisms that eat autotrophs. They are herbivores.

food chain

• Largely feeds on carnivores or secondary consumers.

• Largely feed on primary consumers. Includes omnivores and carnivores.

• A series of steps in which organisms transfer energy by eating and being eaten

• Organism that is able to make its own food

biological magnification

• a change in global or regional climate patterns

• Organism that is able to make its own food

• Organisms that eat autotrophs. They are herbivores.

• increasing concentration of a harmful substance in organisms at higher trophic levels in a food chain or food web
