The population growth is generally described by the following equation : `(dN)/(dt)= rN ((K-N)/(K))` What does 'r' represent in the given equation ?

Options

A. Population density at time 't'
B. Intrinsic rate of natural increase
C. Carrying capacity
D. The base of natural logarithm

Answer

B

Explanation

A population growing in a habitat with limited resources shows a sigmoid growth curve. This type of population growth is called Verhulst-Pearl logistic growth as given by the equation :
`(dN)/(dt) = rN ((K-N)/(K))`
where `N=` population density at time `t , r =` Intrinsic rate of natural increase and `K -` carrying capacity.
