Symbiosis refers to two organisms of different species living together in a close relationship.
There are three types of sybiosis: mutualism, 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 whales for transportation purposes. The whale is not harmed by this.
