Question

The age structure of a population influences populations growth because

• A. Younger females have more offspring than do older females
• B. Different age groups have different reproductive capabilities
• C. More is the number of immature individuals, slower is the growth of population
• D. A shorter generation time results in slower population growth

Answer 1

The correct option is B Different age groups have different reproductive capabilities

Different age groups have different reproductive capabilities. Pre-reproductive individuals are the young individuals which will enter the reproductive age after some time. They are the potential source of increase in population. Reproductive individuals are the ones which are actually adding new members to the population. Post reproductive individuals are older individuals which no longer take part in reproduction.

So, the correct answer is 'Different age groups have different reproductive capabilities'.
