Lab 3: Biodiversity
. This lab will allow you to investigate how various organisms alter their environments. Additionally, it will allow you to assess the health of the ecosystem in which you live through the germination of various seed types. Then, utilize this information to complete Experiments 1 and 2 on the
Lab 3 Reporting Form
. Make sure that all of the following items are completed before submission:
a.
Read through intro material and record your hypothesis for “Experiment 1: Interdependence of Species” on the Lab 3 Reporting Form.
b.
Perform “Experiment 1: Interdependence of Species” using your eScience lab manual and kit. Answer post lab questions 1 through 5 on the Lab 3 Reporting Form.
c.
Record your hypothesis for “Experiment 2: Diversity of Plants” on the Lab 3 Reporting Form.
d.
Complete “Experiment 2: Diversity of Plants” using your eScience lab manual and kit. Answer post lab questions 1 through 5 on the Lab 3 Reporting Form.
All post lab questions for “Lab 3: Biodiversity” should be completed on the Lab 3 Reporting Form. Save your completed Lab 3 Reporting Form as a Word document. The document must be formatted according to APA style, including a title page and references page.

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?
