Question

Which of the following is a density-independent population control? 
A) disease in the environment 
B) parasitism in the environment 
C) predation in the environment 
D) unfavourable chemical changes in the environment

Quizplus · Accepted Answer

Unfavourable chemical changes in the environment, such as pollution or toxic spills, can affect a population regardless of its size or density, making it a density-independent population control. The other options (disease, parasitism, and predation) are density-dependent population controls, meaning their impact on a population is influenced by the population size and density.
