  1. The logistic population growth is expressed by the equation:
    1. dt
      = Nr
      K - N
      dNK
    2. dN
      = rN
      K - N
      dtK
    3. dN
      = rN
      dt
    4. dN
      = rN
      N - K
      dtN
Correct Option: B

The logistic population growth is expressed by the equation

dN
= rN
K - N
dtK

where N is population density at time t, r is the Malthusian parameter (rate of maximum population growth) and K is the so called carrying capacity (i.e. maximum sustainable population). It is a type of population growth when resources are limiting.
