“Rabbits and Wolves” Introduction I will be conducting a computer simulation called “Rabbits and Wolves”. In this experiment I will be interaction with a simple forest ecosystem model that will simply take into account three organisms: rabbits, wolves, and grass. As defined by “Environmental Science- 14th Edition”, an ecosystem is “a set of organisms within a defined area or volume that interact with one another and with their environment of nonliving matter and energy.” I will be using the computer simulation to alter the interactions of the organisms in the ecosystem to see what changes occur. Based on mathematical formulas and probability of certain events occurring, the model predicts the changes in the populations of the three…show more content…
The grass growth rate is 1. Graph 2 Evolution of the Rabbit Population without Predators-Wolves Wolves have been removed from the parameters. The simulation was run for 200 iterations. Graph 3 Evolution of the Rabbit Population with Default Predation and an Initial Decrease in the Grass Rate Initial Grass Rate cut in half. The simulation was run for 201 iterations. Graph 4 Increased Initial Population of Rabbits with Default Predation The initial rabbit population was doubled from 20 to 40. The simulation was run for 200 iterations. Discussion My first objective, to view and interact with a simple scientific computer model, was most definitely accomplished over the course of this simulation. I have done so by changing parameters, observing the simulation, and analyzing the data that was brought about by the simulation. I also determined through my use of the computer model that simple changes to one population in the ecosystem created through this computer model does not change the outcome of the simulation in any major way. On the other hand, if you completely get rid of one of the populations instead of raising or lowering
