A) \[dt/dN=rN\]
B) \[dN/rN=dt\]
C) \[rN/dN=dt\]
D) \[dN/dt=rN\]
Correct Answer: D
Solution :
In J-shaped form of population growth, the density increases in an exponential manner and then a crash occurs or the increase stops abruptly as environmental resistance becomes effective. This is mathematically described by an equation of exponential or geometric increase, which is as follows \[\frac{dN}{dt}=rN\] 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 as the biotic potential of each individual).
