<h2>Exponential Population Growth</h2>
Explanation:
The model of exponential population growth predicts that the per capita population growth rate, r :
d. does not change as the population gets larger.
A population shows exponential growth if there is no limitation on growth. All members have abundant resource availability and the population displays its intrinsic rate of increase.This is also known as geometric growth .In geometric growth, rate of increase is expressed as a constant fraction or an exponent by which a particular population is multiplied.
