A rancher is suspected of shooting wolves near Yellowstone National Park, and you have been enlisted to go have a chat with him. The rancher doesn’t see any benefit to having the wolves there. What do you say?
A. "If there are no predators like wolves, just one pair of jackrabbits can quickly create a population with explosive, logistic growth. Wolves help reduce the fecundity rate, keeping the population at a reasonable level." B. "If there are no predators like wolves, just one pair of jackrabbits can quickly create a population with explosive, exponential growth. Wolves help reduce the carrying capacity, keeping the population at a reasonable level." C. "If there are no predators like wolves, just one pair of jackrabbits can quickly create a metapopulation. Wolves help reduce the biotic potential, keeping the population at a reasonable level." D. "If there are no predators like wolves, just one pair of jackrabbits can quickly create a population with explosive, density-dependent growth. Wolves help reduce the age structure, keeping the population at a reasonable level." Clarify question: What is the key concept addressed by the question?
