Vedclass · Answer

(C) In a sigmoid growth curve,the population growth rate eventually becomes stable as the population reaches the carrying capacity $(K)$ of the environment.At this stage,the mortality rate (death rate) and natality rate (birth rate) become equal to each other.Consequently,the population shows a zero growth rate because the birth rate equals the death rate,not because the death rate exceeds the birth rate.Therefore,the Assertion is correct,but the Reason is incorrect.

Assertion: In a sigmoid growth curve,the population finally stabilizes itself.
Reason: Finally,the death rate increases more than the birth rate.
