Which of the following is not a density dependent factor?

مندرجہ ذیل میں سے کون سا کثافت پر منحصر عنصر نہیں ہے؟

Predation

Drought

Parasitism

None of these

Answer: Drought

Drought is not a density-dependent factor because it affects populations regardless of their size.

Density-dependent factors (like predation, parasitism, and disease) have greater effects as population density increases.
