Consider an idealized biological system consisting of mortal rabbits with some fixed initial number of baby rabbit pairs. After the rabbits become mature each pair begets a new pair every month. Use the controls to explore how the rabbits' life span, age of fertility, and initial number of pairs affect the population growth.
