Biogeochemical cycles and global change
The biological systems that produce the flora and fauna we see in Idaho, the Northwest, and globally rely on three fundamental systems called biogeochemical cycles. These include the hydrologic, oxygen, nitrogen, and carbon cycles that move nutrients between living organisms to non-living objects.
Watch the video below on Biogeochemical cycling (the first part is a lot of detail, but the last half is where he really gets into the biogeochemical cycles) and answer the following questions:
1. What are the six atoms that we need for life to be sustained?
2. Where is the largest water storage reservoir on our planet?
3. Through what process does carbon move from the atmosphere to plants?
4. What are three ways that carbon gets returned to the atmosphere?
5. What important role do bacteria play in the nitrogen cycle?
6. What are the four primary steps described for the phosphorus cycle?
