First, remix this model and rename it, and save it to your public gallery. Before each step, be sure the program is saved and you have clicked Run Code. When you have debugged each step, go on to solve the next problem.
1. Why do I have so many mountain lions?
2. Why is my grass brown?
3. Why don't I have any rabbits when I hit setup?
4. Now that my rabbits set up correctly, why aren't they moving?

6. Why isn't the mountain lion data on the graph?
7. Now see how changing the the amount of energy a mountain lion gets from a rabbit affects the ecosystem.
