Water, Phosphor, and Sulfur Cycles: Introduction (02:50)
The biosphere is made of many organisms with varying roles and interrelated processes. Learn about the sedimentary hydrological cycles. Energy flows through the biosphere in one direction.
Water/Hydrological Cycle (03:36)
Water collects, cleans, and distributes the planet's water flow. Ground water feeds rivers and lakes, and causes soil erosion. Learn timelines for subterranean water flow, surface water flow, and atmospheric water circulation.
Phosphor Cycle (02:35)
Phosphor is a fundamental component of the ATP molecule and forms parts of nucleic acids; it is essential to life. The main phosphor reserves are in rocks on sea beds and the Earth's crust. The phosphor cycle does not form volatile compounds.
Sulfur Cycle (03:59)
This element is found in soil, lakes, and rivers, and is required for biological processes; bacteria are primarily responsible for this cycle. Acid rain negatively impacts the environment. Energy flow is open, but the flow of matter is closed.
Review elements about the water, phosphor and sulfur cycles presented in this video.
