1. Mutualism
Certain types of algae live inside reef-building coral. 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.
