A population of white-footed mice becomes severely overpopulated in a habitat that has been disturbed by human activity. Sometimes intrinsic factors cause the population to increase in mortality and lower reproduction rates in reaction to the stress of overpopulation. Which of the following is an example of intrinsic population control?

#Unit 10. Ecological Principles
  1. Owl populations frequent the area more often because of increased hunting success.
  2. Females undergo hormonal changes that delay sexual maturation and many individuals suffer depressed immune systems and die due to the stress of overpopulation
  3. Clumped  dispersion  of  the  population  leads  to  increased  spread  of  disease  and  parasites  resulting  in  a population crash.
  4. All of the resources (food and shelter) are used up by overpopulation and much of the population dies of exposure and/or starvation.
