Focus Questions: How is carbon transferred through the five basic cycles of our earth? Objectives: 1. Identify the elements/processes in each of the following cycles: carbon, nitrogen, phosphorus, sulfur, and water/hydrological. 2. Contrast and compare the elements /processes of each cycle to one another and identify the common parts. 3. Analyze how the carbon of organisms interact with the biosphere as part of the flow in the biogeochemical cycles (carbon, nitrogen, phosphorus, sulfur, and water cycles). 4. Recognize particular problems that humans are experiencing due to human interference with the cycles."
