Which of the following equations depicts Verhulst-Pearl logistic population growth ?

Options

  1. AdN dt = rN ( K+N K )
  2. BdN dt = rN ( K-N K )
  3. CdN dt = rN ( K-N N )
  4. DdN dt = rN ( K K-N )

Correct answer

B. dN dt = rN ( K-N K )

Step-by-step solution

The Verhulst-Pearl logistic population growth is described by the equation: dN dt = rN ( K-N K ) where N is the population density at time t , r is the intrinsic rate of natural increase, and K is the carrying capacity. Answer: dN dt = rN ( K-N K )
