The experimentation results show that this prediction is true, as the wolf population decreased when their primary food source ceased to exist. However, the wolves would have no food source, therefore they would die out. If there were were more wolves than rabbits, then the grass availability would increase. (Don't forget to reset the simulation before changing the parameters.) (Portfolio) Reverse the hypothesis: What would happen if there were lots more wolves than there are rabbits? Would the wolves live forever? Record your hypothesis, prediction and experiment results.These results matched my prediction and differed from the first run of the simulation as this test took a longer amount of time to balance the populations of rabbits and wolves. Ultimately, the lack of food availability and the increased wold population lead to a decline in the rabbit population. This leads to a decrease in the rabbit and wolf populations. However, there soon is not enough grass to sustain the rabbit population. When the initial number of rabbits is increased, the wolf population also increased. Did your prediction match with the results? How was it different than the first run of the simulation? Adjust the settings to increase the initial number of rabbits. Then click the View/Modify Parameters button followed by the View/Modify Start Parameters.
Experiment: Test the hypothesis by first resetting the simulation.In neither case would the rabbits take over and live forever. A different scenario is that if the rabbit population were increased, then the wolf population would increase as well, causing the populations to balance out. If there were more rabbits than wolves, then most likely the rabbits would consume too much of their food source too quickly and eventually the population would decrease due to a lack of food availability. Hypothesis: What would happen if there were lots more rabbits than there are were wolves? Would the rabbits take over and live forever?.There needs to be a balance between the two animals because if wolves eat too many rabbits then the rabbit population will decrease, causing the wolf population to also decrease. Record your groups observations about how the population of rabbits and wolves changed over time.Īs the population of rabbits increases, the wold population also increases. You can open the population graphs at any point to see how they change over time. On the Activity tab, click Start Simulation.
