The correct answer is C. Natural resources are limited
Step-by-step explanation:
Population growth occurs as the number of individuals increases over time, this is related to reproduction, life expectancy, and other factors such as natural disasters, wars, etc. Besides, uncontrolled or high population growth can become a major issue, this can be explained as the more individuals there are the more natural resources are needed to fulfill their need but the natural resources are limited. In this way, population growth can lead to a shortage of food, water, housing, etc. due to the limitation of natural resources. Thus, population growth is an issue because natural resources are limited and the population can surpass the number of individuals an ecosystem can support (carrying capacity).
