Which of the following is a positive numerical response of a predator in response to an increase in prey density?
A)decrease in predator mortality rate
B)increase in predator survival rate

D)decrease in predator reproduction rate

Question

Quizplus · Accepted Answer

When there is an increase in prey density, predators are more likely to immigrate to an area with high prey density as it increases the availability of food, ultimately leading to an increase in the predator population. Therefore, option C is a positive numerical response of a predator. A decrease in predator mortality rate or an increase in predator survival rate could also be positive responses, but these options are not included in the given choices. A decrease in predator reproduction rate is a negative response.
