Question

The logistic population growth is expressed by the equation:

• A. dt/dN = rN ($\frac{K-N}{K}$)
• B. dN/dt= rN ($\frac{K-N}{K}$)
• C. dN/dt = rN
  
• D. dN/dt= rN ($\frac{N-K}{N}$)

Answer 1

The correct option is B dN/dt= rN ($\frac{K-N}{K}$)

The logistic population growth is expressed by the equation
dN/dt= rN ($\frac{K-N}{K}$)
where,
N is population density at time t
r is the intrinsic rate of natural increase
K is the called carrying capacity (i.e. maximum sustainable population).
