In Verhulst Pearl logistic growth curve equation \(\frac{dN}{dt}\)=rN (\(\frac{\text K-N}{K}\)), 'r' refers to:
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) -Intrinsic rate of natural increase
Verhulst-Pearl Logistic Growth and is described by the following equation:
\(\frac{dN}{dt}\)=rN (\(\frac{\text K-N}{K}\))
Where N = Population density at time t
r = Intrinsic rate of natural increase
K = Carrying capacity
Since resources for growth for most animal populations are finite and become limiting sooner or later, the logistic growth model is considered a more realistic one.
