The formula for exponential population growth is

Options

A. `dt//dN=rN`
B. `dN//rN=dt`
C. `rN//dN=dt`
D. `dN//dt=rN`

Answer

D

Explanation

J-shaped form of population growth is mathematically described by an equation of exponential or geometric increase, which is as follows :
`(dN)/(dt)=rN`
where, d=rate of change
t=time
N=number of females at a particular time
r=biotic potential of each female
(N can also be considered as the total population and r as the biotic potential of each individual).
