1. Read Ch. 5-7 in Visualizing Environmental Science. 2. Discussion Question 1 Due Date: Day 2 [post to the Main forum] (Due 8/19/08)Resource: Appendix C and Ch. 5 (pp. 99-104) of Visualizing Environmental ScienceReview Ch. 5 pp. 99-104 The Flow of Energy Through Ecosystems. Then complete Appendix C. Post your response to the following question: Identify the fruit or vegetable you selected and relate the second law of thermodynamics to the changes in energy observed in Appendix C.
