Topic: Population attributes: growth, birth and death rate, age distribution· Ecology and Environment
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) :
1. when N/K is exactly one.
2. when N nears the carrying capacity of the habitat.
3. when N/K equals zero.
4. when death rate is greater than birth rate.
