Correct answer: B. Unlimited
Explanation: Exponential growth occurs under ideal conditions of unlimited food and space, producing a J-shaped growth curve.
Exponential growth produces an ever-steepening J-curve with no limit, an unrealistic long-term model; logistic growth produces an S-curve that levels off at the carrying capacity K, as growth rate (K−N)/K shrinks to zero once resources are fully used.
Concept context
