What is an ecosystem?
The definition of an ecosystem is a biological community of interacting organisms and their physical environment, involving a complex set of relationships between plants, trees, animals, fish, birds, mirco-organisms, water, soil and people. 

If an ecosystem is healthy, it is described as sustainable.  This means that all elements live in balance, and are capable of reproducing themselves.

A healthy ecosystem has a food chain that provides food for all its inhabitants, from plankton on the bottom, to ducks on the surface.  Larger animals, like deer, come to the surface to drink.

If an animal is lost from the ecosystem, due to extinction, the whole balance will be disrupted.

Animals are important in maintaining a healthy ecosystem.  Beaver dams turn a rushing river into quieter waters, ideal for plants and animals that prefer this type of environment.
