This model simulates the classic Lotka-Volterra equations, describing the cyclic population dynamics between two species: a predator (foxes, red line) and its prey (rabbits, green line). The oscillations occur because high prey numbers lead to increased predator numbers, which in turn causes the prey population to crash, eventually leading to a predator decline. Sliders allow manipulation of birth and death rates, affecting the stability and amplitude of these ecological cycles.
