Question

In logistic growth, as N approaches K the growth rate will .

• A. increase
• B. decrease
• C. not change

Answer 1

The correct option is B decrease

The logistic growth equation is given by:
$\frac{dN}{dt}=rN\left(\frac{K-N}{K}\right)$
where N = Population density at time t
r = Intrinsic rate of natural increase
K = Carrying capacity

When N approaches K, dN/dt will tends to 0. This means that the growth rate will decrease as K approaches N.
