Vedclass · Answer

(A) Exponential growth occurs when resources are unlimited in the habitat. In this model,the population size $(N)$ increases at a rate proportional to the current population size. The rate of change of population size with respect to time is given by the differential equation: $dN / dt = rN$ Where: $N$ = Population size $t$ = Time $r$ = Intrinsic rate of natural increase. Therefore,option $A$ is the correct formula.

Column-$I$ (Value of $r$)	Column-$II$ (Example)
$P. 0.12$	$I$. Flour beetle
$Q. 0.015$	$II$. Norway rat
$R. 0.0205$	$III$. Human population in India in $1981$

The formula for exponential population growth is $:-$
