Question

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?

Answer 1

Answer:

Density-independent regulation

Explanation:

It is given that before the arrival of hurricane, the population of mice has stabilized.  

This means the rate of birth and deaths are approximately equal.  

But as the hurricane came, it disrupted this balance and would have led to a change in both the birth and death rates. This is termed as Density-independent regulation as abiotic factors and environmental factors have affected the birth and death rates
