List of symbiotic relationships. Symbiosis can vary between mutualism, commensalism, and parasitism, though these grade into each other, and it is often difficult to tell which is involved in a given relationship. In 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.
