What does the shape of the given age pyramids reflects about the growth status of the related population ?

Options

A. `{:((i),(ii).),("Expanding","Stable"):}`
B. `{:((i),(ii).),("Stable","Declining"):}`
C. `{:((i),(ii).),("Expanding","Declining "):}`
D. `{:((i),(ii).),("Declining","Stable"):}`

Answer

C

Explanation

Triangular age pyramid has high proportion of preproductive individuals, moderate number of reproductive individuals and fewer post-reproductive individuals. It represents young or rapidly growing population. In urn-shaped age pyramid, the numbe of reproductive individuals is higher than the number of pre-reproductive individuals. It represents declining or diminishing population with negative growth. In bell-shaped age pyramid, the number of pre-reproductive and reproductive individuals is almost equal. Post reproductive individuals are comparatively fewer. It represents stable or stationary population, neither nor diminishing.
