Question

Quizplus · Accepted Answer

Density-dependent factors are those that are influenced by the population density, such as competition for resources, predation, and disease. Option A and B are density-dependent because they depend on the presence and abundance of individuals in the population. Option C is also density-dependent because disease outbreaks are often more severe in areas with high population densities. Option D is not density-dependent because the cold spell is an abiotic factor that affects all plants in the area equally, regardless of population density.
