a form of life composed of mutually interdependent parts that maintain various vital processes.

any organism that exists by preying upon other organisms.

an animal hunted or seized for food, especially by a carnivorous animal.

symbiotic relationship

the living together of two dissimilar organisms, as in mutualism, commensalism, amensalism, or parasitism.

a type of relationship between two species of a plant, animal, fungus, etc., in which one lives with, on, or in another without damage to either.

a relationship between two species of organisms in which both benefit from the association.

a relation between organisms in which one lives as a parasite on another.

a series of organisms interrelated in their feeding habits, the smallest being fed upon by a larger one, which in turn feeds a still larger one, etc.

a series of organisms related by predator-prey and consumer-resource interactions; the entirety of interrelated food chains in an ecological community.

any class of organisms that occupy the same position in a food chain, as primary consumers, secondary consumers, and tertiary consumers.

An autotrophic organism that serves as a source of food for other organisms in a food chain.

A heterotrophic organism that feeds on other organisms in a food chain.

An animal that feeds mainly or only on plants.

An animal that feeds chiefly on the flesh of other animals. Carnivores include predators such as lions and alligators, and scavengers such as hyenas and vultures.

An organism that eats both plants and animals

An organism that feeds on and breaks down dead plant or animal matter, returning essential nutrients to the ecosystem.

an organism, usually a bacterium or fungus, that breaks down the cells of dead plants and animals into simpler substances.

An organism that manufactures its own food from inorganic substances, such as carbon dioxide and ammonia.

An organism that cannot manufacture its own food and instead obtains its food and energy by taking in organic substances

An apex predator is an animal who, as an adult, has no natural predators in its ecosystem. The great white shark is an example of an apex predator.
