Question

Give two or more examples of density-independent factors and density-dependent factors that could affect populations.

Answer 1

Density-independent factors are abiotic factors that affect populations regardless of their size, such as natural disasters (e.g., fires, floods) and weather events (e.g., droughts, extreme temperatures). Density-dependent factors are biotic factors that affect populations based on their size and density, such as competition for resources (e.g., food, water, shelter), predation, and disease.
