Which of these statements best describes the relationship of mutualism between hermit crabs and anemones? A. Hermit crabs and anemones live in the same ecosystem and can eat similar organisms. B. Anemones can move on their own by using their tentacles and pedal disk. The pedal disk is on the side of the anemone that is opposite its mouth. C. Anemones cannot move very quickly, but they can sting predators. When an anemone is riding on a hermit crab’s shell, the anemone protects the crab from predators. D. When hermit crabs grow too big for a shell, they leave it behind and move to a larger shell. If an anemone has attached itself to the old shell, the hermit crab will move the anemone to its new shell.
