What does the following diagram indicate?
(a) Declining population
(b) Expanding population
(c) Steady population
(d) Reproductive isolation
This question was posed to me in an online quiz.
This intriguing question originated from Population Attributes in section Organisms and Populations of Biology – Class 12
Correct choice is (b) Expanding population
The best I can explain: The following pyramid indicates the expanding population. It is a triangular age pyramid in which the individuals in pre-reproductive age are more, moderate in reproductive age while fewer individuals are present in post-reproductive age.
