How to use ecosystem

Ecosystem is used in both scientific and metaphorical contexts. In biology, it refers to specific communities of organisms and their physical environment; increasingly, it is also applied to interconnected networks in business, technology, and other domains to describe complex systems where multiple elements interact and depend on each other. The metaphorical use is neutral and widely accepted in contemporary English.

A common mistake

Learners sometimes confuse ecosystem with habitat, but habitat refers to the physical place where an organism lives, while ecosystem includes both the organisms and their interactive relationships with each other and their environment.
