What is the simplest conclusion about population growth?

Answer and explanation

Correct answer: It shows population change through births, deaths and migration

Correct answer: A. Population growth means the change in the number of people during a particular period. To understand this change, we consider three main components: births add people, deaths remove people, and migration changes the population when people enter or leave an area. Thus, population growth is not limited to births alone. B is wrong because rainfall is a climatic element, not a direct component of population growth. C is wrong because soil texture describes soil, not changes in human numbers. D is wrong because forest height belongs to vegetation study. A useful memory cue is: population change = births − deaths + net migration. Always distinguish population growth from population density, which means people per unit area.
