Exercises 1-6 refer to the following systems of equations: (i) di dy di (ii) dz (1-) - 20ry xy 10x 0.3x dt dy 100 – 15 (1 - ) - 25xy. di 20 1. In one of these systems, the prey are very large animals and the predators are very small animals, such as elephants and mosquitoes. Thus it takes many predators to eat one prey, but each prey eaten is a tremendous benefit for the predator population. The other system has very large predators and very small prey. Determine which system is which and provide a justification for your answer.

1. In one of these systems, the prey are very large animals and the predators are very
small animals, such as elephants and mosquitoes. Thus it takes many predators to
eat one prey, but each prey eaten is a tremendous benefit for the predator population.
The other system has very large predators and very small prey. Determine which
system is which and provide a justification for your answer.
