Dynamic models are mathematical representations that simulate how systems change over time. They are used in various fields, such as economics, biology, and engineering, to predict future behavior based on current conditions and past data. These models often incorporate variables that can change, allowing for a more accurate depiction of real-world processes. In dynamic models, feedback loops and time delays are essential components. For instance, in ecological studies, a dynamic model might illustrate how predator and prey populations interact over time. By analyzing these interactions, researchers can better understand ecosystem stability and the impact of environmental changes.
