In a growing population of the country,
Options
- AReproductive and per-reproductive individuals are equal in number
- BReproductive individuals are less than the post-reproductive individuals
- CPre-reproductive individuals are more than reproductive individuals
- DPre-reproductive individuals are less than the reproductive individuals
Correct answer
C. Pre-reproductive individuals are more than reproductive individuals
Step-by-step solution
In a growing population, the 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 a declining population, and the age pyramid appears urn-shaped. A similar case is seen when reproductive individuals are less than post-reproductive individuals.
