About this app
Predator-Prey Meadow is an interactive ecosystem simulation set in an open meadow, where bunnies move and flee, foxes hunt, and both populations reproduce over time. You draw the starting positions yourself — place a cluster of bunnies here, a pair of foxes there — and watch what unfolds. As bunnies multiply, foxes have more to eat and their numbers grow; as foxes become more numerous, bunnies come under heavier pressure and their population falls, which then leaves foxes short of food, and the cycle begins again. This boom-and-bust rhythm mirrors the Lotka-Volterra equations, a predator-prey model from mathematical biology — but here the rhythm plays out directly through individual bunnies and foxes rather than through equations. See if you can find a starting arrangement in which bunny and fox numbers settle into a steady back-and-forth rhythm, rather than spiraling into a crash.
