How to Determine Whether Population Growth Is Logistic or Exponential?
Exponential growth occurs when there are no barriers to growth such as limited resources. The logistic growth model shows growth as it approaches the maximum capacity the environment can sustain; as the population gets closer to the limit, the rate of increase decreases. If you have narrowed down the growth rate options to either logistic or exponential, you can determine which growth pattern the group follows by comparing the changes in the growth rate.
