The document summarizes the sulfur cycle. It describes sulfur as an essential element for life found in amino acids. It then outlines the key components involved in the cycle, including sulfur dioxide, sulfate, and hydrogen sulfide. The cycle involves volcanic emissions of sulfur dioxide, which disperses in the air or decomposes to hydrogen sulfide. It can then precipitate to land or water where it is used by plants and enters the food chain before eventually settling as sediments or being released again by volcanic eruptions.

5. Is this cycle balanced?

6. The effects of too much sulfur

7. The Sulfur Cycle Before we get started on the sulfur cycle, we need to know what sulfur is anyway. SULFUR is.... An element

8. An essential element of life

9. Used in fertilizers, gunpowder, pesticides and fungicides

10. Found in two amino acids: cysteine and methionine

11. The Sulfur Cycle Why do we need it? Sulfur is an important nutrient for organisms, being a key constituent of certain amino acids, proteins and other biochemicals. Plants get sulfur by acquiring simple mineral compounds from the soil. Animals then get the organic form of sulfur by eating plants or animals who eat plants. Sulfur is also an important mineral commodity. It is obtained through pollution control in factories where it is collected in its natural gas state. Then it may be used for sulfate fertilization in some prairie agriculture.
