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?

Post-Lab Questions

1. Restate your hypothesis. Was it confirmed or denied? How do you know?

2. How many different kinds of species did you find in your sample?

3. Which species is the most numerous in your sample area? Which is the least numerous?

4. If each peat pot was a sample you found in a group of wildflowers, would you determine based on the diversity of flowers that the ecosystem is healthy?

5. How does biodiversity contribute to overall health of an ecosystem?
