Question

In a growing population of a country,

• A. pre-reproductive individuals are less than the reproductive individuals.
• B. pre-reproductive individuals are more than the reproductive individuals.
• C. reproductive and pre-reproductive individuals are equal in number.
• D. reproductive individuals are less than the post-reproductive individuals.

Hint:

The individuals in a population can be divided into three age groups: pre-reproductive, reproductive, and post-reproductive age groups. The triangular-shaped graph is observed in developing countries as the pre-reproductive population is more there. 

Answer 1

The Correct Option is B

In a growing population of a country, pre-reproductive individuals are more than reproductive individuals.

Whenever the population is of a growing or expanding type, the population of pre-reproductive individuals or the younger population is very large. The reproductive population will be moderate whereas the post-reproductive individuals are very few. Thus, the rate of growth will depend on the size of the pre-reproductive population.
