A) \[dt/dN=Nr\left( \frac{K-N}{K} \right)\]
B) \[dN/dt=rN\left( \frac{K-N}{K} \right)\]
C) \[dN/dt=rN\]
D) \[dN/dt=rN\left( \frac{N-K}{N} \right)\]
Correct Answer: B
Solution :
[b] The logistic population growth is expressed by the equation \[\frac{dN}{dt}=rN\left[ \frac{K-N}{K} \right]\] 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.
