The shape of pyramids gives the reflection of growth status of a population. Identify the growth status depicted by the given pyramid. |
Expanding Declining Exploding Stable |
Expanding |
The correct answer is Option (1) -Expanding A population at any given time is composed of individuals of different ages. If the age distribution (per cent individuals of a given age or age group) is plotted for the population, the resulting structure is called an age pyramid. The shape of the pyramids reflects the growth status of the population - (1) whether it is growing, (2) stable or (3) declining. The age pyramid of an expanding population has a broad base as the number of pre-reproductive individuals is higher when compared to other age groups. The reproductive individuals are moderate in number and individuals of post-reproductive age group are less. Representation of age pyramids for human population |
