Explanation

According to the law of population growth, given by P. F. Verhulst, the rate of increase in a population per unit time depends on the population size, the innate capacity to increase and the  unutilized opportunity for population growth. He defined it with a formula – dN/dt = rN where N is the number of individuals in a population, dN/dt is the rate of change of its numbers, over time and r is the intrinsic rate of natural increase in a population.
