Symbiotic Relationships

Details on the 3 types of symbiosis


Mutualism is a symbiotic relationship in which both organisms involved are benefited from the relationship. There is only a positive effect from this symbiosis. Mutualism is used in about 48% of all land plants. Many species would not be capable of living in the way they do without certain mutualistic symbiotic relationships.


Parasitism is a symbiotic relationship that is not mutually beneficial. It usually between a host and parasite. The parasite is the one that benefits from while the host is harmed. Not enough to die because the parasite depends on a host for life. They exploit the health of a host for their own gain and generally reproduce faster than the host.


Commensalism is the symbiotic relationship where one party benefits while the other neither harmed nor helped. Usually these relationships consist of an organism using another to get food, while the other receives nothing.
These are just some examples of these symbiotic relationships. There's many more that occur in nature.
