==Description==

==Description==

The term '''symbiosis''' (from the [[Greek]]: σύν syn "with"; and βίωσις biosis "living") commonly describes close and often long-term interactions between [[different]] [[biological]] species. The term was first used in 1879 by the German mycologist [http://en.wikipedia.org/wiki/Heinrich_Anton_de_Bary Heinrich Anton de Bary], who defined it as "the living together of unlike [[organisms]]." The definition of symbiosis is in flux, and the term has been applied to a wide range of biological interactions. The symbiotic relationship may be categorized as [http://en.wikipedia.org/wiki/Mutualism_(biology) mutualistic], [http://en.wikipedia.org/wiki/Commensalism commensal], or [http://en.wikipedia.org/wiki/Parasitism parasitic] in [[nature]]. Others define it more narrowly, as only those relationships from which both organisms benefit, in which case it would be synonymous with mutualism.

Symbiotic relationships include those [[associations]] in which one organism lives on another ([http://en.wikipedia.org/wiki/Ectosymbiosis ectosymbiosis], such as mistletoe), or where one [[partner]] lives inside the other ([http://en.wikipedia.org/wiki/Endosymbiont endosymbiosis], such as lactobacilli and other bacteria in [[humans]] or zooxanthelles in corals). Symbiotic relationships may be either obligate, i.e., necessary for the [[survival]] of at least one of the organisms involved, or facultative, where the relationship is beneficial but not [[essential]] for survival of the organisms.[http://en.wikipedia.org/wiki/Symbiosis]
