Why are there so few lions compared to wildebeest in africa? Explain this in terms of ecological efficiency and energetic hypothesis
Suppose that hares are the only prey and food supply of bobcats, and that the predator‒prey interaction follows Lotka‒Volterra dynamics. The mortality rate of bobcats in the absence of rabbits is 0.1 per month. The intrinsic growth rate of rabbits in the absence of predators is 0.2 per month. The attack efficiency of bobcats is 0.004. The efficiency at which hare biomass is converted into bobcat biomass is 0.25. If there are 60 bobcats and 400 hares, the instantaneous rate of change in the hare population will be a ____________ per month, and the instantaneous rate of change in the bobcat population will be a ____________ per month.
A. loss of 16 hares; loss of 6 bobcats
B. loss of 16 hares; gain of 18 bobcats
C. gain of 16 hares; gain of 6 bobcats
D. gain of 80 hares; gain of 24 bobcats
E. loss of 96 hares; gain of 6 bobcats

- Suppose that blue sheep are the most important prey of snow leopard, and that the predator‒prey interaction follows Lotka‒Volterra dynamics.

Snow leopard capture efficiency is 0.002, and the efficiency at which blue sheep biomass is converted into snow leopard biomass is 0.2.
