E)B, C, and D

Question

Quizplus · Accepted Answer

All three options B, C, and D make prey populations vulnerable to predation and increase the probability of extinction. Prey populations are stressed by additional environmental factors (B), making them less able to cope with predation pressure. Predators that are new to the prey's habitat (C) may not be recognized as a threat and catch the prey species off guard. Prey species that are long-lived and have low birthrates (D) may not be able to keep up with predation and may not recover quickly enough if their populations are decimated. Additionally, predation pressure can be especially strong when predators and prey have coevolved over long periods of time (A), but this option is not as strong as the other three and is not the best choice.
