Ecosystems are made up of all the living and non-living things that interact in an environment. Living things live in specific environments because they can find food, water, and shelter. An ecosystem consists of organisms, populations, and communities. Organisms are individual animals or plants, populations are groups of the same kind of organism in one place, and communities are all the populations living together in an ecosystem.
