Summary Introduction
Introduction:
There is a kind of relationship between the predators and prey. The predators are those who feed on prey and the prey is the victim eaten by predators. For survival, the predators depend upon the prey and are responsible for reduction in the population of prey.

Inthe Lotka-Volterra predation model, a prey (host) population in the absence ofpredators would:a.grow exponentially.b.grow logistically.c.grow exponentially, and then crash when it has outstripped its own foodsupply.d.decline to extinction.e.the model makes no assumptions about what happens in the absence ofpredators.
Which statement is a valid analysis about bison movement and the carrying capacity of Yellowstone National Park?
A.
The decrease in the northern herd's population is explained by its inability to migrate and the park's decreasing carrying capacity.
B.
The fact that bison only migrate in years of deep snow indicates that they have exceeded the park's carrying capacity.
C.
The carrying capacity for other animals found in Yellowstone has increased due to the bison's migration outside of the park.
D.
The movement of bison beyond park boundaries is not due to the bison population being too large for the park's carrying capacity.
Part B:
Which selection from the text provides evidence that directly supports this analysis?
A.
They move to lower elevation ranges during the winter months in response to snow accumulation and snowpack development.
B.
The model integrates data from several ecosystem-related variables,…
