The correct option is(c) pre-reproductive individuals are more than the reproductive individuals
Explanation:
In a growing population. younger population (or pre-reproductive individuals) size is larger than that of reproductive individuals. Such a population is represented by a triangular-shaped age pyramid.
Whereas. the equal number of reproductive and pre-reproductive individuals represents a stable population and the age pyramid is bell-shaped.
Less number of pre-reproductive individuals than reproductive individuals represents declining population and age pyramid appears urn-shaped. The similar case is seen when reproductive individuals are less than the post-reproductive individuals.
