What are Terrestrial Ecosystems? An ecosystem refers to the interrelation of biotic and abiotic factors. In simpler terms, an ecosystem is an entity where living organisms interact with the physical environment.

An ecosystem can be categorized into two major types: aquatic ecosystems and terrestrial ecosystems.
