Lesson Summary. Parasitism defines a relationship between two organisms where one is harmed, and the other benefits. There are several different types of parasitism, and these are defined by how the parasite interacts with a host.arasitism describes a relationship between two organisms where one benefits, and the other is harmed.
Symbiosis is a relationship between two or more organisms that live closely together. There are several types or classes of symbiosis: Commensalism One organism benefits and the other is neither harmed nor helped. Mutualism Both organisms benefit. An obligate mutualist cannot survive without its partner; a facultative mutualist can survive on its own. Parasitism One organism (the parasite) benefits and the other (the host) is harmed. To be successful, a symbiotic relationship requires a great deal of balance. Even parasitism, where one partner is harmed, is balanced so that the host lives long enough to allow the parasite to spread and reproduce. These delicate relationships are the product of long years of co-evolution.
