Suppose That a Predatory Fish Eats Only Minnows and the Predator‒prey

question 9

Multiple Choice

Suppose that a predatory fish eats only minnows and the predator‒prey interaction follows Lotka‒Volterra dynamics. The intrinsic growth rate of minnows in the absence of predators is 0.2 per month, and the mortality rate of the predatory fish in the absence of minnows is 0.1 per month. The capture efficiency rate is 0.004, and the efficiency at which minnow biomass is converted into predator biomass is 0.25. The predatory fish population will increase only if the number of minnows is

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