Which of the following most logically completes the passage?
A certain species of coral that flourishes on a reef off the North Carolina coast provides shelter for more than 300 species. Among these species is a crab that feeds on the reefs abundant seaweed. These crabs are able to survive on the reef only because the coral provides crannies in which they can hide to escape their many predators. The provision of benefits, however, extends in both directions, since ___________.
A. crabs of this species are rarely found among coral that grows in waters deeper than those of the reef off North Carolina
B.crabs of this species cannot survive in a well-lit area if no corals grow there
C. no other species that find shelter among corals off the North Carolina coast compete with crabs of this species for food
D.the unfettered growth of seaweed severely inhibits the growth of corals
E. this species of coral secretes a substance that is nutritious to crabs and other crustacians
