An ecosystem is a unit in which the life-cycles of living organisms are linked to each other, as well as to the non-living constituents of the environment to form a dynamic, interactive natural system.

Ecology is a broad discipline comprising many sub-disciplines, so issues ranging from environmental to social to political to technological etc. are often informed by ecological perspectives and analysis. Below is an example of a social media ecosystem.
