Question

Algae grows on manatee's skin. The manatee is not affected. Is this an example of commensalism, mutualism, parasitism, or predation

Answer 1

This specific example would be classified as an example of commensalism. In commensalism, one species benefits while the other is neither harmed nor benefited. In this case, the algae benefits by finding a surface to grow on (the manatee's skin), while the manatee is not affected by the presence of the algae.
