B. The organisms in the ecosystem did not compete for resources
Explanation: The wolves are the keystone species of the Yellowstone ecosystem. They prey on other organism, hence, maintain a balance in the forest. in case, the wolves are removed, the animals, which are the prey of the wolves would increase, which may lead to increase in competition and exploitation of the resources and eventually an unbalanced ecosystem. Hence, the wolves are very important to Yellowstone.
