Question

Which of the following is an example of a density-independent factor limiting population growth? A. A forest fire that was caused by lightning B. The presence of predators C. An outbreak of wasting disease in elk D. Competition for food

Answer 1

 presence of predators

Answer 2

Answer;

A forest fire that was caused by lightning

Explanation;

-Density-independent factors are factors such as weather and climate, that exert their influences on population size regardless of the population's density. In contrast, the effects of density-dependent factors intensify as the population increases in size.

-Density-independent limiting factor have the same effect regardless of population size, for example - If there is a wild fire, the fire destroys all the animals in the forest regardless of how many animals there are. The fire does not care how big the population is.
