In symbiosis, at least one member of the pair benefits from the relationship. The other member may be injured (parasitism), relatively unaffected.

Symbiotic relationships may be between two organisms of similar sizes or of differing sizes, and most of the processes under symbiosis, encompassing mutualism through parasitism have child terms to specify the sizes of the organisms involved. These terms use the nomenclature host for the larger organism and symbiont.
