Symbiosis is the interaction between two living things. Sea anemones team up with clown fish. The sea anemones give the fish shelter and protection; and the fish eats scraps and lures food to the anemone’s tentacles. Resurrection ferns benefit from the tree but don’t kill the tree. Hermit crabs let anemones grow on their backs, so the anemones get scraps and the crab’s protection.
