Post-Lab Questions
1. Restate your hypothesis. Was it confirmed or denied? How do you know?
2. Indicate which species was removed during each round of the experiment.
3. Explain how the ecosystem was affected by the missing species for each round of the experiment.
4. What actions do we as humans engage in that can lead to extinction of any of these components?
5. What can we do to minimize our impact on the ecosystem?
