What can happen to population growth when death rate decreases?

Answer and explanation

Correct answer: Growth may increase

Direct answer: A, growth may increase. Population changes mainly through births, deaths and migration. If the death rate decreases while births and other conditions remain comparable, fewer people are removed from the population through death. More people survive, so the total population can rise faster or decline more slowly. Option A is correct because it states a possible effect, not an unavoidable result; the exact change also depends on births and migration. Option B is wrong because a lower death rate does not make the birth rate zero; births and deaths are different measures. Option C is wrong because population counting continues regardless of the death rate. Option D is wrong because migration means movement of people and is not made impossible by fewer deaths. Memory cue: fewer deaths usually support population increase, but remember that total growth also depends on births and migration.
