We have been looking at things that have an affect on environments. One of the things discussed was the inclusion of other species and how this alters the food chain within an environment.
Here is a little interactive activity to view how two species interact within an environment.
See if you can alter the parameters (e.g. how many rabbits/wolves there are to begin the game)
to have the two species living in a balanced environment so that rabbits,
wolves and grass continue to survive comfortably.
