From Wikipedia, the free encyclopedia. This is a list of mutualistic symbiotic relationships, in which different species have a cooperative or mutually dependent relationship. This relationship can be either external or endosymbiotic, whereby an organism resides in another's body or cells.n mutualism, both organisms benefit. In commensalism, one benefits and the other is unaffected; in parasitism, one benefits and the other is harmed. Some of these relationships are so close that we speak of the composite of two species as one unit; for example, we speak of the composite of algae and fungi as lichens.
