What is the relation between population growth and death rate?

Answer and explanation

Correct answer: Death rate affects growth

Direct answer: A, death rate affects population growth. Death rate indicates the number of deaths in a population during a specified period. Deaths remove people from the population, so a higher death rate generally reduces natural increase, especially when other factors remain similar. A lower death rate can allow the population to grow more quickly if births exceed deaths. Option A is correct because death rate is a real component of population change. Option B is wrong because a river is a physical feature, not a rate of deaths. Option C is wrong because death rate does not increase land area; area is a separate geographical measurement. Option D is wrong because death rate has a clear demographic meaning. The final population also depends on births and migration, so death rate alone cannot explain every change. Memory cue: natural change is linked to births minus deaths; migration must then be considered separately.
