Slowing growth of biological organisms as resources are depleted

The correct answer is: Logistic growth

• In logistic growth, a population's per capita growth rate gets smaller and smaller as population size approaches a maximum imposed by limited resources in the environment, known as the carrying capacity ( K).
• Exponential growth produces a J-shaped curve, while logistic growth produces an S-shaped curve.
• Yeast, a microscopic fungus used to make bread and alcoholic beverages, exhibits the classical S-shaped curve when grown in a test tube (Figure 19.6a). Its growth levels off as the population deplete the nutrients that are necessary for its growth.
