The textbook predator-prey cycle: 40 hares, 9 lynx. Energy is conserved — populations orbit forever.

What will the orbit do?
In classic LV, orbits in the (x, y) plane are closed loops — energy is conserved. Add a carrying capacity (mode = Logistic prey) and the orbit spirals inward to the equilibrium dot. Try it.
