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