In Lotka-Volterra predator-prey models, predator populations decrease when

Question

Quizplus · Accepted Answer

In Lotka-Volterra predator-prey models, the equation for the change in predator population (dP/dt) is given by (amN - m)P, where N is the prey population, a is the predator's attack rate on prey, and m is the predator's natural mortality rate. Setting dP/dt = 0 and solving for N gives N = m ÷ ac. Thus, if the prey population falls below N = m ÷ ac, the predator population will decrease as they are unable to consume enough prey to sustain their population. Choice C is the closest to this value.
