Quizplus · Accepted Answer

A numerical response in predators is primarily a change in their numbers due to factors that directly affect their population size, such as birth rates (population growth) and movement of individuals into (immigration) or out of (emigration) the area. Changes in prey abundances influence the functional response, which is how predator feeding rates change with prey density, rather than directly altering predator numbers through birth or movement.
