Introduction:
The carrying capacity can be defined as the maximum number of organisms that can be supported by the resources present in a certain environment. All the physical factors such as temperature, food availability, presence of gases in the environment and the amount of waste determine the carrying capacity.

How do humans differ from other species in the ability to “choose”a carrying capacity for their environment?
If the rate of some process is governed by the abundance of prey individuals, we say that it is prey-dependent. Give some examples of prey-dependent processes.
Carrying capacity is the maximum number of animals an environment can support. Looking atyour graph, what do you think the carrying capacity for deer might have been? Why?

- 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 bobcatsarrow_forwardinterpret the following graph: In the graph, the number of days are 18.. 1 day is equal to 60 sec. days are taken on x-axis.
