This Grassland simulation gives you control over many factors in an ecosystem. Set up a population using the controls on the left, adjust its properties using the controls at the bottom, and see what happens! If you have a hypothesis, put it to the test! Feel free to try things on a whim as you start out. If you would like some specific help in planning your procedure, click here!
