Symbiosis Everywhere!!!!!!!!!!!!!!!!!!!!!!!!!

In science class we learned about symbiosis. Symbiosis is a relationship with two living organisms. There three types of symbiotic relationships. The first one is mutualism which is a relationship when both organisms benefit. The second one is commensalism which is a relationship when one organism benefits and the other is neutral. The last one is parasitism which is a relationship when one organism benefits and the other is harmed. In parasitism there is a parasite and a host. The organism benefiting is the parasite. The organism being harmed is the host. An interesting fact about parasitism is it has many forms. Some parasites kill their host. Some keep their host surviving. Half of all animals have at least one parasitic phase in their life cycles. I believe that symbiosis is one of the most interesting parts of the world. Animals depend on this kind of relationship to survive.
