These questions regard the last 4 lectures of the course. There will be more questions on the final exam representative of this portion of the course, so especially try and be fluent on the material covered on this review worksheet. Good luck on the final exam, and I hope SI was fun and beneficial to you all this semester!
Ecosystems: Lectures Dec. 2 and Dec. 5
