Population dynamics is the study of the size and age composition of populations. This simulation produces data for population size over time for three different species in a simple food chain; a plant, a herbivore, and a predator. The starting populations, as well as the reproductive rates and the amount of food needed by the herbivore and predator, can be controlled by the user. Worksheets are available for both a guided lab and an inquiry option. Check out the blog post for more information on the design and use this simulation.
