plant. This is an example of

A small group of mice were released on an island. The island previously
had no mice on it, but had abundant food and no predators. After
several years of growth, the size of the new island population stabilizes.
However, at this point a hurricane drastically reduces the population.
How would you describe the situation?
A. The biotic potential of the population has been reduced. B. The new
population size is a result of density-dependent regulation.
C. The new population size is a result of density-independent
regulation.
D. The island mouse population can now act as a sink metapopulation.
C. The new population size is a result of density-independent
regulation.
