Explain the S-shaped pattern of population growth. How is J-shaped pattern different from it and why?
S-shaped pattern of population growth form shows an initial gradual increase, followed by an exponential increase and then a gradual decline to a near constant level. It is different from J-shaped curve because J-shaped pattern shows exponential population growth and its abrupt crash after attaining the peak value.
A-When resources are not limiting the growth, plot is exponential.
B-When resources are limiting the growth, plot is logistic, ATis the carrying capacity.
