In ecology, the word ecosystem is an abbreviation of the term, ecological system.

Some consider this the basic unit in ecology.

Ecosystems are not to be confused with biomes because they are smaller than biomes.

They can be as big as the Sahara Desert, but as small as a pond.

The term microecosystem may be used to describe a very small (often closed)ecosystem.
