symbiosis

Two species coexisting

Two organisms live in symbiosis when one supplies an essential element to the other, or each supplies an essential element to the other.

The organism we call lichens, for example, is actually a fungus and an alga living in symbiosis.

People use symbiosis more generally to talk about any relationship in which two things contribute to each other in a way that fosters dependency.
