Population Growth Simulator

The equations give one smooth curve, but real populations are made of individuals who live and die by chance. This simulator runs both side by side, so you can see how close they stay and when a small population dies out anyway.

What you can do

  • Exponential and logistic growth with a carrying capacity you set
  • An individual-based run in which every individual lives, breeds and dies by chance
  • Predator and prey as a Lotka-Volterra mode, with a phase plot
  • The equations beside the graph, with your values put in
  • Worked answers for N after a time, doubling time, per capita rate, rate from two readings, fastest growth and K, each marked on the curve
  • Practice questions in the style of exams, with full working
