Investigate the constant flow of energy from the sun to Earth and among living and non-living states. Students will explore key nutrient cycles from birth to death and beyond and see how human behavior can affect these cycles. The program also breaks down the atmosphere into its major components of carbon,  oxygen, nitrogen, and phosphorus and investigates how each of these elements is used in the biosphere. Finally, a case study of a coffee farm allows viewers to understand how this knowledge can help a farmer maximize output while minimizing   influence on the environment.
