Today we did a simulation lab of predators and preys in class. The purpose of the lab is to find out the relations between number of predators and number of preys in a specific environment, and we used wolfs and rabbits as our subjects. We used large and small cards as our wolves and rabbits. In the first round, 1 large card and 3 small cards are put into the environment. Each time a wolf card is put into the environment, it has to touch three rabbit cards in order to reproduce, while the rabbit cards continue to reproduce each round. Here is our data after 10 rounds of simulation.
As you can see, the number of wolves didn't grow until the 5th round, while the number of rabbits shows a significant increase during the first 5 rounds. The decrease in number of rabbits didn't start until the 7th round, which is when we begin to see a larger increase in number of wolves. I believe that this represents that the number of predators is directly proportional to number of preys in the beginning, but becomes more indirectly proportional as the number of preys begins to decrease while number of predators is rising.
