Question
Which of the following equations depicts Verhulst-Pearl logistic population growth?
Options
A.$\frac{dN}{dt} = rN\left( \frac{K + N}{K} \right)$.
B.$\frac{dN}{dt} = rN\left( \frac{K - N}{K} \right)$
C.$\frac{dN}{dt} = rN\left( \frac{K - N}{N} \right)$
D.$\frac{dN}{dt} = rN\left( \frac{K}{K - N} \right)$
Solution
Sol. [Key Concept: Verhulst–Pearl logistic growth equation]
Verhulst-Pearl logistic population growth is depicted by the equation $\frac{dN}{dt} = rN\left( \frac{K - N}{K} \right)$
Where
- K = Carrying capacity
- r = Intrinsic rate of natural increase
- N = Population density at time 't'
