A biocoenosis (alternatively, biocoenose or biocenose ), terme by Karl Möbius in 1877, describes all the interacting organisms living together in a specific habitat (or biotope). Biotic community , biological community, and ecological community are more common synonyms of biocenosis, all of which represent the same concepts. Two additional words coined by analogy are zoocoenosis for the faunal community and phytocoenosis for the floral community within a biotope. The extent or geographical area of a biocenose is limited only by the requirement of a more or less uniform species composition.
