POST LAB QUESTIONS
1. Develop a hypothesis on which pot you believe will contain the highest biodiversity.
2. Based on the results of your experiment, would you reject or accept the hypothesis that you produced in question 1? Explain how you determined this.
3. Assume each pot represents a sample that you found in a group of wildflowers. Based upon the diversity of flowers present in each pot; would you say that the ecosystem is healthy? Why or why not?
4. How does biodiversity contribute to the overall health of an ecosystem? Provide specific examples and utilize at least one scholarly resource to back your answer.
