Currently a national park has a high elk population of 40,000. The carrying capacity is estimated to be at 30,000. For over 100 years wolves have been absent in the park due to over-hunting. This year park rangers intend to fly in 20 wolves to the park and set them lose to establish territories. No hunting is allowed in the park. Using the above scenario predict the limiting factors of both the elk and the wolves. Include information about effects on their populations.
