All the different populations of organisms that live and interact in the same area.

A large ecological area with similar climate and a specific set of plants and animals (e.g., deserts, forests, grasslands).

The green pigment in plants that absorbs sunlight during photosynthesis.

An animal that is hunted and eaten by another animal.

An organism that gets its energy by eating other organisms.

The role and position a species has in its environment, including how it meets its needs for food and shelter.
