Question

The population growth is generally described by the following equation:
$\frac{dN}{dt}=rN\frac{(}{K-N}K)$
What does'r' represent in the given equation ___________________.

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

Answer 1

The correct option is B Intrinsic rate of natural increase

A population growing in habitat with limited resources shows a sigmoid growth curve. This type of population growth is called verhuladt-pearl logistic growth as given by the equation:
$\dfrac{dN}{{dt} = rN\dfrac ({K-N}{K})$
When, N = population density at time t; r = Intrinsic rate of natural increase and K = caring capacity
