The title is deliberately playful.
The ecology, discipline very serious and complicated, located in the mathematics of differential equations support.
In particular a “classical” equation (or system of equations) is used to describe the dimanica between prey and predator.
These are the Lotka-Volterra equations em>.
For the numerical solution of these equations we have chosen a tool a tool “Open source software for numerical computation”.
It is used for the dynamic simulation environment Xcos.
A request file is available implementation of mathematical equations in this environment.
