As the cattle graze and move around the field, insects are disturbed and fly up that are then caught and eaten by the cattle egret. This is an example of ___________. • parasitism • commensalism • mutualism Orchids are found in dense tropical forests, where sunlight does not easily reach the floor of the forest. Orchids solve this issue by growing with their base attached to the branches of trees, thus raising themselves up to access adequate sunlight and gather any nutrition that flows down the branches of the tree. As orchids do not grow very large, the tree is not harmed by this attachment. This is an example of ___________. • parasitism • commensalism • mutualism Remora fish are small fish that have suckers on their fins allowing them to attach to sharks, whales, and sea turtles. They use the larger sea organism as transportation and protection from other predators. The remora fish also eat any scraps of food that remain when the larger organism eats its prey. This is an example of ___________. • parasitism • commensalism • mutualism
