Population Growth Models (Logistic & Exponential) – AP Biology

1. In logistic growth, the population growth rate dN/dt is maximum when:

N = K N = K/2 N = 0 N = 2K

2. When N is very small relative to K, logistic growth approximates:

Linear growth Exponential growth No growth Decline

3. The carrying capacity K is determined by:

The initial population size The growth rate r Available resources and environmental limits The number of predators only
