CORE DEFINITION

Symbiosis (pl.: symbioses) is any close and long-term biological interaction between two organisms of different species. In 1879, Heinrich Anton de Bary defined symbiosis as "the living together of unlike organisms". The term is sometimes more exclusively used in a restricted, mutualistic sense, where both symbionts contribute to each other's subsistence. This means that they benefit each other in

Mechanistically, both parties exchange resources (nutrients, protection, dispersal) to reduce their respective survival costs, making the overall fitness higher than if each fended for itself.
