Zoology - Organisms and Populations Question with Solution | TestHub

Exponential growth form can be represented mathematically by the following exponential equation: $$\frac{dN}{dt}=(\mathrm{B}-\mathrm{D})\times \mathrm{N}$$ $\mathrm{B}=$ Birth rate, $\mathrm{D}=$ Death rate Let $(B-D)=r$ or intrinsic rate of growth. Then, $=r\times n$ where $d$ is the rate of change, $\mathrm{N}=$ number of existing individuals. $t=$ time and $r=$ intrinsic rate of natural increase represents the rate of change in population size.
