Which of the following scenarios represents a density-independent limit on population?

• Caribou population growth is limited as a result of grass depletion.

• Porcupine population growth is limited by the spread of disease.

• Box turtle population growth is regulated by a hurricane that destroys their nests.

• Woodpecker population growth is regulated by opossum predation of woodpecker eggs.

Which population is limited by a density-dependent factor?

• A deer population is reduced as a result of a forest fire.

• A local wolf population experiences a lethal epidemic of parvovirus.

• Many eggs in a population of frogs are destroyed due to a drought.
