Answers (1)

Figure A shows a population, in which the ratio of individuals in pre-reproductive age is highest, following by reproductive age and post-reproductive age. This pyramid shows a growing population.

Figure B shows a population in which the number of individuals in pre-reproductive and reproductive age is equal. A number of individuals in post-reproductive age is less. This pyramid shows a stable population, i.e. population growth, is negligible.

Figure C shows a population in which the number of individuals in pre-reproductive age is the least. The number of individuals in reproductive age is the highest. Less number of individuals in pre-reproductive age shows a negative growth rate in the population. This pyramid shows a population in de-growth.
