Creative Writing Assignment
Imagine yourself as a native species in the Great Lakes. Describe your home. What does it look like? What do you eat? What do you do everyday?
Suddenly a new species comes to town. This species eats the same food as you and may like to live in the same environment as you? What do you do? Where did this species come from and how did it get there? Do you have any adaptation that can help you? Are you able to eat another food? If you can, what else eats that food? Will you survive or not?
