Which population growth model describes a situation where population growth slows or stops after a period of exponential increase?

• A. Linear growth model
• B. Logistic growth model
• C. Exponential growth model
• D. Geometric growth model

Answer: (B)

Verified step by step guidance

1. Understand the key characteristics of each growth model: Exponential growth involves rapid population increase without limits, Logistic growth includes a carrying capacity where growth slows or stops, Linear growth is steady and constant, and Geometric growth involves proportional increases.
2. Focus on the logistic growth model, which is characterized by an initial phase of exponential growth followed by a slowdown as the population approaches the carrying capacity of the environment.
3. Recognize that the carrying capacity is the maximum population size that the environment can sustain due to limited resources such as food, space, or water.
4. Visualize the logistic growth curve: It starts with a steep upward slope (exponential growth), then transitions into a plateau as the population stabilizes near the carrying capacity.
5. Conclude that the logistic growth model best describes the scenario where population growth slows or stops after a period of exponential increase.
