9/21 - Continue Ch 2

Today we continued with the notes on Chapter 2. We focused on the four cycles:
1. Nitrogen Cycle
2. Carbon/Oxygen Cycle
3. Phosphorus Cycle
4. Water Cycle

Then we went over how humans can interact with these cycles.

Section 3 dealt with ecology, which we defined. Then we talked about ecosystems, energy transfer, food chains, and food webs.

Tomorrow we will finish up Ch2, and we will have a lab on Ch 2.

**I have also uploaded the CHapter 2 review sheet to the Earth and space folder. If you want to print it out now, you can. Also, if you lose the one that I give you, you will need to print out a copy from the folder (click on the link at the top of the page, and click on Chapter 2)
