The activity is designed to illustrate the species relationships in a food chain and the effect of predators on the trophic levels below. In fact, maximum population growth rate (G) occurs when N is half of K. Yeast is a microscopic fungus, used to make bread and alcoholic beverages, that exhibits the classical S-shaped logistic growth curve when grown in a test tube (Figure \(\PageIndex{3}\)). This should make intuitive sense, but should also be clear from the geometric growth rate equation, and the fact that r = b-d in the model. Populations grow and shrink and the age and gender composition also change through time and in response to changing environmental conditions. Environmental scientists use two models to describe how populations grow over time: the exponential growth model and the logistic growth model. The growth rate of a population is the average number of female offspring that each female produces over the course of her lifetime. NGSS Life Science offers many great lessons.
