Barnacles are marine organisms that live attached to surfaces as adults. A scientist studies two barnacle species that live on rocks on a coast in Scotland. In some rocky areas Species A is found alone. In other rocky areas Species B is found alone. In still other rocky areas both species are found together. The diagram below shows the two barnacle species on rocks in their habitats. If Species B were removed from the rocky areas it shares with Species A, Species A would most likely inhabit —

• Zone I only

• Zones I and II only

• Zone III only

• Zones I, II, and III
