consider the following systems of rate of change equations system A : dx/dt=3x(1-x/10)-1/20xy , dy/dt=-5y+xy/20, system B: dx/dt=3x-xy/100, dy/dt=15y(1-y/17)+25xy. in both of these systems,x and y refer to the number of two different species at time t.In particular, in one of these systems, the prey is large animals and the predators are small animals, such as piranhas and humans. Thus it takes many predators to eat one prey, but each prey eaten is a tremendous benefit for the predator population....
