Suppose that rabbits are the only prey and food supply of foxes, and that the predator‒prey interaction follows Lotka‒Volterra dynamics. The mortality rate of foxes in the absence of rabbits is 0.1 per week, and the intrinsic growth rate of rabbits in the absence of predation is 0.2 per week. The capture efficiency is 0.002, and the efficiency at which rabbit biomass is converted into fox biomass is 0.2. If there are initially 30 foxes and 400 rabbits, the overall rate of change in the rabbit population will be a of per week. Group of answer choices gain; 56 loss; 24 loss; 16 gain; 80

gain; 56 loss; 24.

Explanation:

Lotka‒Volterra dynamic is a kind of dynamic which shows the interaction between two organisms i. e. one is predator and the other is prey. Populations of both organisms are dependent on each other. If one population is increased the other organism population will be reduced due to more feeding. Rabbit population grows double than it is reduced due to feeding by foxes. Decrease occurs in the population of foxes due to death which increases the population of rabbit in that ecosystem.
