6 The following question has two parts. First, answer Part A. Then, answer Part B. Part A: 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…

Figure 45.10b If the major food source of the seals declines due to pollution or overfishing, which of the following would likely occur? The carrying capacity of seals would decrease, as would the seal population. The carrying capacity of seals would decrease, but the seal population would remain the same. The number of seal deaths would increase but the number of births would also increase, so the population size would remain the same. The carrying capacity of seals would remain the same, but the population of seals would decrease.
