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.
