What does the following diagram indicate?
(a) Declining population
(b) Reproductive isolation
(c) Steady population
(d) Expanding population
I have been asked this question during an interview.
This key question is from Population Attributes in chapter Organisms and Populations of Biology – Class 12
Right choice is (a) Declining population
To explain I would say: The above pyramid indicates that it is a declining population. It is an urn-shaped pyramid in which more number of individuals is present in reproductive age as compared to pre-reproductive age. It indicates the negative growth of the population.
