Final answer:
Mutualism is a symbiotic relationship where both species benefit, such as clownfish and sea anemones. Commensalism involves one species benefiting and the other being unaffected, while parasitism benefits one species to the detriment of the other.
Step-by-step explanation:
Mutualism is a type of symbiotic relationship where two species interact closely and both benefit from the relationship. An example of mutualism is the relationship between clownfish and sea anemones, where the fish receive protection from predators using the anemone’s stinging tentacles, and the anemones get food particles from the fish’s waste.
On the other hand, commensalism is a symbiotic relationship where one species benefits while the other remains unaffected, such as cattle egrets foraging for insects stirred up by grazing mammals. Parasitism is a third type of symbiosis where one organism, the parasite, benefits at the expense of the other, the host, which is harmed.
