Ecosystem

An ecosystem is composed of living(Biotic) and nonliving things in an area.(Abiotic)

Ecosystem is derived from the Greek word oikos, for “house,” eco-is the combining form meaning “environment or habitat.”

An Ecosystem may be very small such as:

A backyard A pond A

playground A school

Some may be very large like: The deserts of Africa The rain forest of Brazil The saltwater oceans

All ecosystems have the same factors or components
