When does the growth rate of a population following the logistic model equal zero? The logistic model is given as $d N / d t = r N (1 - N / K) :$ NEET 2016 (Phase 1)

Options:

Answer:

Solution:

In logistic growth model population growth equation is described as $\frac{d N}{d t} = r N (\frac{K - N}{K})$

Where,

$N =$ Population density at time t

r=Intrinsic rate of natural increase

$K =$ Carrying capacity

When $\frac{N}{K} = 1$ then

$\frac{K - N}{K} = 0$

Therefore,

$\frac{d N}{d t} = 0$
