Q2. Suppose the rate of plant growth on Isle Royale supported an equilibrium moose population of 300 moose. In this scenario, there are no wolves present, and the environment is stable. One day, 200 additional moose arrive on the island. What would you predict the moose population size to be 30 years later

See the answer below

Explanation:

Since the rate of growth of plants on the island is in equilibrium with moose population and the environment is stable, the addition of 200 moose will not change the population size for the said period.

The environment is relatively stable and the moose's population is in equilibrium with it. It means that the island has reached the maximum number of moose it can support which is 300. If additional 200 moose were to be added, density-dependent population factors (such as competition) will act on the population of moose to keep the population relatively stable around the carrying capacity.

Hence, the population size 30 years later will remain relatively stable at around 300 moose.
