Symbiosis
Animal Behavior
General Description
Symbiosis is an interaction between two different organisms living in close physical association. The three types of symbiosis are mutualism, commensalism, and parasitism.
Mutualism
Mutualism is the way two organisms of different species exist in a relationship in which both benefit from each other. One example of a mutualistic relationship is that of the oxpecker (a kind of bird) and the rhinoceros or zebra. Oxpeckers get food and the beasts get pest control.
