improved, defined and gave examples of the three types of symbiosis
'''Symbiosis''' refers to two [[organism]]s of different [[species]] living together in a close relationship.
There are three types of sybiosis: [[mutualism]], [[parasite|parasitism]], and [[commensalism]].
There are three types of sybiosis: [[mutualism]], [[parasite|parasitism]], and [[commensalism]].
In mutualism, both organisms benefit from the relationship. For example, the clownfish often resides within the tentacles of sea anemones. The clownfish has a place to live, and also wards off butterfly fishes, which eat sea anemones.
In parasitism, one organism benefits while the other suffers. An example is a [[mosquito]] biting a human.
In commensalism, one organism benefits while the other is unaffected. An example is how [[barnacles]] attach to [[whale | whales]] for transportation purposes. The whale is not harmed by this.
