The virus introduced to the island in 1982 that reduced the wolf population is an example of a density dependent factor.
In ecology, a density-dependent factor, also known as a regulatory factor, is any force that modifies the size of a population of living creatures in response to population density.
Because of their propensity to maintain population densities, density-dependent factors are also known as regulating factors.
Population size and a density-dependent factor's level of control are correlated, therefore an increase in population will increase the influence of the limitation. Density-dependent factors involve biotic factors such as availability of food , predation, competition, parasitism and disease.

Answer:
C
Explanation:
Air flowing from areas of high pressure to low pressure creates winds. Warm air can hold more moisture than cold air. Air moving at the bases of the three major convection cells in each hemisphere north and south of the equator creates the global wind belts.
