If deaths are more than births what effect can occur on population?

Answer and explanation

Correct answer: Natural decrease can occur

Direct answer: A, natural decrease can occur. Natural change is found by comparing births and deaths. If deaths are more numerous than births, the calculation births − deaths gives a negative result. This means the population may decrease naturally, before considering migration. A is correct because it describes this negative natural change. B is wrong: more deaths do not make a population double; they can reduce it. C is wrong because the physical area of a place does not automatically change when its population changes. D is wrong because a higher death rate does not make the birth rate disappear; births may still continue. Migration can later increase or decrease the total population, but it does not change the fact that deaths exceeding births produce natural decrease. Memory cue: more deaths than births means a minus sign.
