Because coral contain calcium carbonate deposits, one situation poses a growing threat to coral as well as the many organisms that are dependent on them. That situation is A) the disappearance of certain species of fish due to overfishing. B) the deposition of calcium on the reefs, due to the leaching of calcium from dead organisms. C) over exposure to sunlight due to the relatively shallow nature of the ocean around the reefs. D) acidification of the ocean caused by increased atmospheric carbon dioxide emissions that dissolve in water.
