What is the difference between parasitism and symbiosis?


Symbiosis is a close relationship between two species in which at least one species benefits. Mutualism is a symbiotic relationship in which both species benefit. 

In a symbiotic relationship, the organisms are mutually benefited. No organisms are hurt. Example algae and fungi. 

Parasitism is a symbiotic relationship in which one species (the parasite) benefits while the other species (the host) is harmed. A parasitic relationship is one in which one organism, the parasite, lives off of another organism, the host, harming it and possibly causing death. The parasite lives on or in the body of the host.

A few examples of parasites are tapeworms, fleas, and barnacles. Tapeworms are segmented flatworms that attach themselves to the insides of the intestines of animals such as cows, pigs, and humans.
