Natural increase is related to which two processes?

Answer and explanation

Correct answer: Births and deaths

Direct answer: Option A, births and deaths. Natural increase means the change in population produced by the difference between the number of births and the number of deaths in a place during a period. It does not include people moving into or out of the place. Step by step: a birth adds one person to the population, while a death removes one person. Therefore, natural increase is calculated as births minus deaths. If births are greater than deaths, the natural increase is positive; if deaths are greater, there may be a natural decrease. Option A is correct because it names both processes used in this calculation. Option B is wrong because in-migration and out-migration describe movement and together show net migration, not natural increase. Option C is wrong because rainfall and temperature are climate elements. Option D is wrong because soil and minerals are natural resources, not population processes. Memory cue: natural increase comes from natural events—births and deaths; movement between places is migration.
