Which graph shows logistic growth?

Which graph shows logistic growth?

• A. J Curve Graph
• B. Exponential Graph
• C. Linear Graph
• D. S Curve Graph

Answer: (D)

Logistic growth is represented by an S-shaped curve. It starts with rapid growth when the population is small and resources are abundant, then slows as crowding increases and resources become limiting, finally leveling off as the carrying capacity of the environment is reached. This slowing and leveling off distinguishes it from other patterns: a J-shaped or exponential curve keeps rising without bound, while a linear graph increases at a constant rate without leveling off. So the graph that shows logistic growth is the one with the S-shaped curve.
