Exponential growth form can be represented mathematically by the following exponential equation: dtdN=(B−D)×N B= Birth rate, D= Death rate Let (B−D)=r or intrinsic rate of growth. Then, =r×n where d is the rate of change, N= number of existing individuals. t= time and r= intrinsic rate of natural increase represents the rate of change in population size.
The formula for exponential population growth is:
