Background: Symbiosis, is a close relationship between organisms of different species in which one or both of the organisms benefit. There are 5 types of symbiosis: • Parasite, is an organism that lives in or on another organism (Host). • Mutualism, in this relationship both organisms benefit. • Commensalism, one organism benefits and the other organism is neither helped nor harmed. • Neutralism, where organism neither benefits nor get harmed. • Predation, happens when one organism hunts/predates another organism. One benefits and the other gets harmed.
