Final answer:
Logistic growth occurs when a population grows rapidly initially but eventually levels off due to limited resources. An example of logistic growth is seen in yeast, a microscopic fungus that exhibits the classical S-shaped curve when grown in a test tube.
Step-by-step explanation:
Logistic growth occurs when a population grows rapidly initially but eventually levels off due to limited resources.
It is a more realistic model of population growth compared to exponential growth.
The growth rate starts exponential, then slows down as resources become limited, and finally levels off at the carrying capacity of the environment.
An example of logistic growth is seen in yeast, a microscopic fungus used to make bread and alcoholic beverages. In a test tube, yeast growth exhibits the classical S-shaped curve.
Initially, it grows rapidly but levels off as the population depletes the nutrients necessary for its growth.
