How would the introduction of a predator species affect the stability of an
 ecosystem?
 A. The native prey might not be able to protect itself against the new
 predator, so the prey population would probably decline rapidly.
 B. The stability would not change because the new predator would
 simply replace the native predator.
 C. The new predator would be unable to hunt effectively for native
 prey, so the stability would not change.
 D. The stability of the ecosystem would increase as a result of the
 introduction of a new predator species.
