With the help of suitable diagram describe the logistic population growth curve.

Explanation

It is more common form of growth. There is an initial period or lag phase of slow growth. It is followed by log phase or exponential Phase. As environmental resistance comes into play, the growth curve shows a point of inflection. Thereafter growth slows down and reaches an equilibrium or stagnant phase. At this time the population size has reached the point of carrying capacity of the habitat - asymptote.
