ECOLOGY

Which of the following statements about how density- dependent and density-independent factors affect population growth is TRUE? The effect of most density-dependent factors on population growth is greater when populations are small. The effect of most density-dependent factors on population growth is greater when populations are large. The effect of most density-dependent factors on population growth is not related to population size. The effect of most density-independent factors on population growth is greater when populations are large.

Solution

Answer:

The effect of most density-dependent factors on population growth is greater when populations are large.

A limiting factor that depends on population size is called a density-dependent limiting factor. Density-dependent factors operate only when the population density reaches a certain level. These factors operate most strongly when a population is large and dense. They do not affect small, scattered populations as greatly.
