NEET 2025 Botany Logistic Growth MCQ Question

Type: MCQ-conceptual-Medium-Class 12

Which one of the following equations represents the Verhulst-Pearl Logistic Growth of population?

A

dNdt=r(K−NK)\frac{dN}{dt} = r\left(\frac{K - N}{K}\right)

B

dNdt=rN(K−NK)\frac{dN}{dt} = rN\left(\frac{K - N}{K}\right)

C

dNdt=rN(N−KN)\frac{dN}{dt} = rN\left(\frac{N - K}{N}\right)

D

dNdt=N(r−KK)\frac{dN}{dt} = N\left(\frac{r - K}{K}\right)

Correct Answer

Option B

Detailed Explanation

The Verhulst-Pearl Logistic Growth equation is dNdt=rN(K−NK)\frac{dN}{dt} = rN \left( \frac{K⁻N}{K} \right), where r is the intrinsic growth rate, N is the population size, and K is the carrying capacity.
