An ecosystem is a community of living and non-living things that function together. Within an ecosystem, organisms are interdependent and adapted to the environment. Ecosystems can be as large as a desert or a sea or as small as a tree or a pond. Examples of ecosystems are coral reefs, rainforests, deep seas, deserts, tundra, savanna and urban centers like our cities.
