Read “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 ecosystems based upon their biodiversity. Then, you will utilize
this information and your eScience lab kit to complete Demonstration 1 and
Experiment 1 on the Week Three Lab Reporting Form. Make sure to complete all of
the following items before submission:
