What is the difference between exponential and logistic growth?

• Exponential growth is linear, logistic growth is constant

• Exponential growth is unlimited, logistic growth is limited by carrying capacity

• Exponential growth decreases over time, logistic growth increases

• Exponential growth is slow, logistic growth is fast
