An ecosystem is all the organisms living in a particular area and all the non-living (abiotic_ conditions.

A habitat is just where an organism lives.

Ecosystems are self-supporting; maintain themselves. Water, nutrients and carbon are all recycled.

Only thing it needs is an energy source i.e. sun.
