The logistic population growth is expressed by the equation

A

$dt / dN = Nr (\frac{K-N}{K})$

B

$dN / dt = rN (\frac{K-N}{K})$

C

$dN / dt = rN$

D

$dN / dt = rN (\frac{N-K}{N})$

(AIPMT-2011)

Solution

(b) : Logistic population growth is expressed by following equation:

$dN / dt = rN (\frac{K-N}{K})$

Where, $N$ = population density at time $t$

$r$ = intrinsic rate of natural increase

$K$ = carrying capacity
