Logistic Growth Equation

Q. In a population that exhibits logistic growth, increment in the population size at each point in time is calculated by the formula $\frac{dN}{dt}=rN\left(\frac{K-N}{K}\right)$.

1. True
2. False

Q. When does the growth rate of a population following the logistic model equal zero? The logistic model is given as $\frac{DN}{dt}$ $=rN(1-\frac{N}{K})$

1. When $\frac{N}{K}$ is exactly one
2. When N nears the carrying capacity of the habitat
3. When $\frac{N}{K}$ equals zero
4. When death rate is greater than birth rate
