Question

When does the growth rate of a population following the logistic model equal zero ? The logistic model is given as dN/dt = rN(1-N/K):
A. When N/K equals zero
B. When death rate is greater than birth rate
C. When N/K is exactly one
D. When N nears the carrying capacity of the habitat.

Answer 1

Correct Answer - C
`(dN)/(dt)=rN(1-N/K)`
If N/K is equal to 1, then
`(dN)/(dt)=rN(1-1)=rN(0)=0`
