Symbiosis (from Greek συμβίωσις "living together", from σύν "together" and βίωσις "living")[2] is any type of a close and long-termbiological interaction between two different biological organisms, be it mutualistic,commensalistic, or parasitic. The organisms may be of the same or of different species. In 1879, Heinrich Anton de Bary defined it as "the living together of unlike organisms".
Symbiosis can be obligatory, which means that one or both of the symbionts entirely depend on each other for survival, or facultative (optional) when they can generally live independently.

Mutualism or interspecies reciprocal altruismis a relationship between individuals of different species where both individuals benefit.[17] In general, only lifelong interactions involving close physical and biochemicalcontact can properly be considered symbiotic. Mutualistic relationships may be either obligate for both species, obligate for one but facultative for the other, or facultative for both.
