The algae provide the coral with nutrients in return for protection. 2. Commensalism Barnacles attach themselves to a whale’s skin. The barnacles benefit from constant movement of water past the swimming whale, which carries food particles to them. The whale is not helped or harmed. 3. Predation An anglerfish has a body part that looks like a fishing lure, which it uses to lure unsuspecting smaller fish close to its mouth. Then, it captures and eats the fish. 4. Parasitism Fleas live on the skin of a dog and bite it to feed on its blood. The fleas benefit by having a host that provides a food source, while the dog is harmed. 5. Amensalism In a pasture, sheep and cattle make trails in grass that they trample, and without realizing it, they kill the grass. The sheep and cattle are not affected because there is plenty of other grass to feed on.
