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

Options

  1. AdNdt=r(K−NK)\frac{d N}{d t}=r\left(\frac{K-N}{K}\right)
  2. BdNdt=rN(K−NK)\frac{d N}{d t}=r N\left(\frac{K-N}{K}\right)
  3. CdNdt=rN(N−KN)\frac{d N}{d t}=r N\left(\frac{N-K}{N}\right)
  4. DdNdt=N(r−KK)\frac{d N}{d t}=N\left(\frac{r-K}{K}\right)

Correct answer

B. dNdt=rN(K−NK)\frac{d N}{d t}=r N\left(\frac{K-N}{K}\right)

Step-by-step solution

Logistic growth is described by Verhulst-Pearl logistic growth equation dNdt=rN(K−NK)\frac{d N}{d t}=r N\left(\frac{K-N}{K}\right).
