Multiple Choice

Suppose that a lizard species eats only one type of insect and the populations follow Lotka‒Volterra dynamics. The intrinsic growth rate of insects in the absence of predators is 0.2 per week and the mortality rate of the lizards in the absence of insects is 0.05 per week. The capture efficiency rate is 0.002, and the efficiency at which insect biomass is converted into predator biomass is 0.2. The insect population size will increase only if the number of lizards is

A) above 50.
B) above 100.
C) below 50.
D) below 100.
