  3. Phosphorus • Phosphorus is a vital nutrient necessary for plants and animals in the form of PO43- and HPO42-. • Phosphorus is the building block of important parts of the body such as bones and teeth. • About 80% of the world’s phosphorus is used in fertilizers and soft drinks. • Phosphorus does not entre the atmosphere it stays in rocks and soil minerals.

  4. Phosphorus • Unlike other cycles of matter compounds, phosphorus cannot be found in atmosphere as a gas. • It usually cycles through water, soil, and sediments.

  5. Phosphorous Cycle • First phosphorus is eroded off of rocks and deposited in the soil. • Now in the soil, phosphorus is absorbed into the clay and other organic material within the soil. • Next plants dissolve the ionized phosphates in the soil. • Then the phosphates are absorbed by herbivores when they consume the plants and then into carnivores when they eat the herbivores. • Finally phosphorus is deposited back into the soil when plants and animals decay or through animal waste.

  7. Human Effects • The mining of phosphate ores for fertilizer affects the time cycle of the phosphorus cycle. • Mining results in the premature release of phosphates into the cycle which can cause an abundance of algae to form and cause hypoxia. • Normal levels of Phosphorus in surface water .01 to .03 mg/l
