- 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.
