Consider the two systems of differential equations dr (1) = 0.3z - 0.1ry = 0.3r - 3ry dt dy dt = -0.1y +2ry = -2y + 0.1zy dt One of these systems refers to a predator-prey system with very lethargic predators-those who seldom catch prey but who can live for a long time on a single prey (for example, boa constrictors). The other system refers to a very active predator that requires many prey to stay healthy (such as a small cat). The prey in each case is the same. Identify which system is which and justify your answer.
