Question

Quizplus · Accepted Answer

A viral disease is a density-dependent factor because its impact on population growth increases as the population density increases. As more individuals are in close proximity to each other, the disease can spread more easily and have a greater impact on the population. The other options (elevated temperature, prolonged winters, and a devastating forest fire) are density-independent factors, meaning their impact on population growth is not related to population density.
