Symbiosis is a close, long-term relationship among two or more species that live and interact together. There are 3 types of Symbiotic Relationships: 1) Mutualism - A special type of relationship in which one organism feeds on and lives in or on another organism. Thus, the parasite and the host organism coexist. 2) Commensalism - A relationship in which both members benefit but one member is not harmed. 3) Amensalism - A relationship in which one member neither benefits nor is harmed, but the other organism is affected.

One species may live in close association with another species. If these organisms share resources then this arrangement is called symbiosis. Symbiosis in which both species benefit from the association is called mutualism. If the association is beneficial to one species but neither benefits nor harms the other, it is called commensalism. If one species benefits at the expense of the other, then the relationship is called parasitism. Bacteria living in the gut of termites, receiving protection and nutrients and supplying the termite with enzymes to digest cellulose is an example of commensalism mutualism coevolution competition parasitism

In a commensal relationship: a) one species pollinates the other. b) neither species benefits or is harmed, but the community itself benefits. c) one species provides nutrients, usually cellulose, for the other. d) one species benefits while the other neither benefits nor is harmed. e) the "loser" has reduced reproductive output.
