Hypothesis
If a predator is restricted in forging range and has a limited food supply then the predator that is not limited will have a higher survivorship than that of the predator that is restricted. a. H0: If a predator is restricted in forging range and has limited food supply, there will be no difference in survivorship as a predator who is not restricted. HA1: If a predator is restricted in forging rand and has a limited food supply then the predator that is restricted will have a higher survivorship than a predator that is not restricted. HA2: If a predator is restricted in forging range and has a limited food supply then this predator that is restricted will have a lower survivorship than a predator that is not restricted.

Discussion:
Our group simulation looked at survivorship of predators, who were spoons, and what happens if restrictions were placed on predators. One predator was restricted by a 1ft x 1ft square, or tile, where 50 prey, or beans, were placed inside the square with the predator. If the beans were pushed out of the square, the spoon(s) who were restricted would not be able to eat the bean because it was out of their forging range. On the outside, another 50 beans were placed for the spoons (predators) who were not restricted, these predators were allowed to eat both inside and outside of the square. After each 20 second round, the amount of prey captured for restricted and non-restricted were counted separately yo determine the amount both sides of predators would have in a 6 binding cap from the start. Our groups results seemed very conclusive. We rejected our null hypothesis and accepted our HA1 hypothesis. By the end of the simulation, only one non-restricted predator was able to survive. The restricted predators already knew that because they were restricted they had to move fast before their prey was stolen while the...
