One of the simplest examples of a changing quantity is the number of plants or animals of a particular species. Modeling can predict that a species is headed for extinction, and can indicate how the population will respond to intervention.
Populations grow according to the number of individuals that are capable of reproduction.
At the same time, their growth is limited according to scarcity of land or food, or the presence of external forces such as predators. In this module, we examine simple differential equations that model populations. All rights reserved.
