There are three types of symbiotic relationships.  Commensalism is a relationship in which one organism involved in the relationship is helped and the other is neither helped nor harmed.  Parasitism is a relationship in which one orgamism is helped and the other is harmed.  MUTUALISM is a symbiotic relationship in which both species involved in the relationship benefit from it.

B) Mutualism

Symbiosis is a close relationship between organisms of different species in which ONE or BOTH the organisms benefit. Symbiotic relationship has three types: Parasitism, Mutualism and Commensalism

Parasitism is a kind of relationship in which one species benefits while the other is harmed.  On the other hand, MUTUALISM, is the type of relationship in which BOTH organisms benefit. An example of this is the pollination of flowers by bees. As bees get nectar they also help the flowers pollinate. Lastly, commensalism is the relationship in which one organism benefits and the other organism is neither helped nor harm.
