Solution

## The correct option is A Nt=N0 ertA population growing in a habitat with unlimited resources exhibits exponential growth. This exponential growth model results in a ‘J’ - shaped growth curve, when population density (N) is plotted in relation to time ‘t’. Population density is the number of people per unit area (per square kilometre). In the exponential growth model, the curve representing rate of change of population density is represented as dN/dt = rN where, dN represents the change in the population density dt represents the change in time ‘t’ r represents the intrinsic rate of natural increase. It is the difference between the birth rate and death rate in a population. This can be represented in the integral form as follows Nt =N0 ert Where, Nt is the Population density after time t N0is the population density at time zero r is the intrinsic rate of natural increase e is the base of natural logarithms
