Mutualism is a term used to describe a symbiotic relationship in which both organisms benefit from the relationship. The domestication of horses by humans is an example, where the humans protect and feed the animals in exchange for their labor. Examples in nature include certain kinds of birds that feed on parasites of large animals. The bird gains a meal and protection, while the animal stays free of unhealthy pests.
