Total mass of living matter at each trophic level.

Ecosystems within areas of similar climate and similar organisms.

This layer of Earth and the atmosphere in which organisms can live.

Non-living factors (water, rocks, etc.).

An example of a consumer, specifically one that eats animals.

The largest number of individuals in a species that an environment can support over a long period of time.

This is a stable group of organisms that is mature with little change in the kinds of species that live together.

A type of symbiotic relationship between two organisms. This type involves one organism that benefits and one organism that is neither benefitted or harmed.

Organisms that do not produce their own food.

The study of all interrelationships between organisms and their environment.

Biological communities and all nonliving factors in the environment.

The physical area where an organism lives.

An organism that eats only plants.

An organism that eats other organisms because they cannot produce their own food.

A biotic or abiotic factor that limits the number and distribution of a population.

A type of symbiotic relationship in which both organisms in the relationship benefit.

The role that an organism plays in a place.

A consumer that eats both plants and animals.

A symbiotic relationship in which one benefits and the other is harmed.

A group of organisms of the same species that occupy the same geographic place at the same time.

A type of community interaction in which an organism (predator) captures and feeds on another organism (prey).

An autotroph, an organism that uses sunlight for photosynthesis or inorganic chemicals for chemosynthesis.

A type of community interaction. A close physical relationship between two different organisms.

The feeding position in a food chain such as primary producers-herbivore, primary consumer-omnivore, etc.

Gradual change in a community over time.

An organism that produces food from inorganic materials using an energy source.
