question 14

Multiple Choice

A population of white-footed mice becomes severely overpopulated in a habitat that has been disturbed by human activity.

Which of the following is an example of intrinsic population control?

• A) Owl populations frequent the area more often because of increased hunting success.
• B) Females undergo hormonal changes that delay sexual maturation, and many individuals suffer depressed immune systems and die due to the stress of overpopulation.
• C) Clumped dispersion of the population leads to increased spread of disease and parasites, resulting in a population crash.
• D) All of the resources (food and shelter) are used up by overpopulation, and much of the population dies of exposure and/or starvation.
