Foxes and Rabbits: A Greenfoot Simulation

The Foxes and Rabbits simulation is a fascinating example of predator-prey ecosystems, where foxes and rabbits interact with each other in a virtual environment. This article will delve into the details of this simulation, exploring how it works and what insights it can provide.

To begin the simulation, simply press the GO button. You can adjust various slider parameters to modify the starting conditions, such as the number of each species, amount of grass, maximum age, and number of offspring in a litter. These factors will determine whether the system is stable or unstable.

In this simulation, grass grows at a fixed rate, and when it's eaten, a fixed amount of energy is deducted from the patch where the grass was consumed. Foxes and rabbits wander randomly around the landscape, searching for food sources to replenish their energy levels. Each step costs both animals energy, and if they run out, they die.

The model explores the stability of predator-prey ecosystems by examining how different starting conditions affect population dynamics. By allowing each fox or rabbit to have enough energy to produce offspring and splitting the energy amongst themselves, this simulation creates a realistic representation of natural systems.
