Question:

Which of the following equation is correct about Verhulst-Pearl Logistic Growth?

Show Hint

The Verhulst-Pearl Logistic Growth equation describes the growth of a population in a limited environment. It accounts for the carrying capacity (K), which is the maximum population size that the environment can support. The equation is given as:

\(\frac{dN}{dt} =rN (\frac{K - N}{K})\)

Where:

\(\frac{dN}{dt}\) is the rate of change of the population size,

\(N\) is the current population size,

\(K\) is the carrying capacity (maximum population size the environment can support),

\(r\) is the intrinsic growth rate (rate of reproduction).

This equation shows that as the population NNN approaches the carrying capacity KKK, the growth rate slows down, reflecting the limitations of resources.

  • \( \frac{dN}{dt} = (h - d) \frac{K - N}{K} \)
  • \( \frac{dN}{dt} = rN \frac{N - K}{K} \)
  • \( \frac{dN}{dt} = rN \frac{K - N}{K} \)
  • \( \frac{dN}{dt} = (h - d) \frac{N - K}{K} \)

The Correct Option is C

Solution and Explanation

The Verhulst-Pearl logistic growth model describes population growth where resources are limited. The correct equation for logistic growth is \( \frac{dN}{dt} = rN \frac{K - N}{K} \), where N is the population size, r is the intrinsic growth rate, and K is the carrying capacity. This equation predicts an S-shaped growth curve as the population approaches K.
