Which factor is typically density dependent in populations?

Explanation:
Density-dependent factors are those whose impact grows as the number of individuals increases. Predation rate fits this idea because when a population is large, there are more individuals for predators to encounter, so the amount of predation pressure tends to rise and help regulate the population. Weather events like storms, temperature changes, and natural disasters, on the other hand, affect populations regardless of how many individuals are present, so they are density-independent.
