What is the relation between population growth and birth rate?

Answer and explanation

Correct answer: Birth rate can affect growth

Direct answer: A, birth rate can affect population growth. Birth rate is the number of live births in a population during a specified period, usually expressed in relation to the population. When more births occur, new members are added to the population. If the death rate and migration do not offset those additions, a high birth rate can make population growth faster. Option A is correct because it describes this relationship without claiming that birth rate is the only factor. Option B is wrong because soil is a physical resource, not a demographic rate. Option C is wrong because area measures the extent of land and is used with population to calculate density. Option D is wrong because a mountain is a landform. Birth rate is important, but births, deaths, and migration should be considered together. Memory cue: births add; deaths subtract; migration can add or subtract.
