Final answer:
The exponential growth model results in a J-shaped curve, which represents rapid and continuous population growth in an environment with unlimited resources.
Step-by-step explanation:
The exponential growth model shows a J-shaped curve because the population isn't limited by resources. In this model, when there are unlimited resources such as food and water, a population can grow exponentially.
This means the population size increases dramatically and the growth rate keeps accelerating over time, represented by a J-shaped curve.
In contrast, when resources become limited, the population exhibits logistic growth, which is depicted as an S-shaped curve. This curve has three phases: rapid growth with ample resources, slowing growth as resources become scarce, and leveling off at the environment's carrying capacity—when the population size stabilizes due to resource limitations.
