Ecosystem diversity refers to the diversity of a place at the level of ecosystems. The term differs from biodiversity which refers to variation in species rather than ecosystems. Ecosystem diversity can also refer to the variety of ecosystems present in a biosphere, the variety of species and ecological processes that occur in different physical settings.
