What is the main basis of population growth?

Answer and explanation

Correct answer: The process of addition to and reduction of population

Direct answer: A, the process of addition to and reduction of population. Population changes when people are added through births or in-migration and when people are removed through deaths or out-migration. In simple form: population change equals additions minus reductions. If additions are greater than losses, population grows; if losses are greater, it declines; if they are balanced, it may remain stable. Option A is correct because it includes the main demographic processes behind change. Option B is wrong because climate has no colour that directly measures population growth. Option C is wrong because forest size alone does not count people entering or leaving. Option D is wrong because road width is an infrastructure feature, not a population process. Memory cue: count who comes in and who goes out, including births and deaths.
