The formula for exponential population growthis

$dN/dt = rN$

$dt/dN = rN$

$dN/rN = dt$

$rN/dN = dt.$

(AIPMT-2006)

Solution

(a) : Nearly all populations will tend to grow exponentially as long as there are resources available. The formula for exponential population growth is $dN/ dt = rN$. In this equation $d$ is the rate of change, $N$ is the number of existing individuals, $r$ is the intrinsic growth rate, $t$ is time, and $dN/dt$ is the rate of change in population size.
