Question: How do bears get the nutrients they need to live?
1. Explore: Using the Gizmo, try to figure out what bears depend on for nutrition.
2. Form hypothesis: How do bears get the energy and nutrients they need?
3. Predict: Based on your hypothesis, which population(s) would be hurt if bears were added?

The return of the wolf to yellowstone national park will probably affect the bird population to some degree, not significantly. while wolves will hunt birds when necessary, they prefer to hunt larger prey. the bird population will most likely only be affected when hunting is scarce for the wolves. birds of prey will also probably not be affected as much as other birds who spend more time on the ground hunting for food as the tend to spend more time in the air or in trees since they do not need to stay on the ground for long due to the nature of the way they hunt.
