Symbiosis Symbiosis means a close relationship between two organisms of different species that benefits one or both of the organisms

Parasitism Parasitism is a symbiotic relationship in which one organism benefits and the other organism is harmed

Mutualism is a symbiotic relationship in which both organisms benefit

Commensalism Commensalism is a symbiotic relationship that benefits one organism and does not harm or help the other organism
