Which graph shape is associated with logistic growth?

• A. J Curve Graph
• B. S Curve Graph
• C. Line Graph
• D. Pie Chart

Answer: (B)

The concept being tested is how population growth changes when resources are limited, producing a logistic growth pattern. In logistic growth, the population rises quickly when there are plenty of resources, but as individuals compete for food, space, and other needs, the growth rate slows and the curve bends, eventually leveling off near the carrying capacity of the environment. This creates an S-shaped (sigmoid) graph, reflecting the transition from rapid growth to a steady state as limits are reached. The other shapes don’t capture this dynamic: a J-shaped curve shows unchecked exponential growth with no slowing, a simple line graph isn’t specific to growth over time, and a pie chart represents parts of a whole rather than changes over time.
