Transcript of "Phosphorus cycle"

  1. 1. PHOSPHORUS CYCLE Group Members Imran Zardari (12IEEM12) Muhammad Fahad Ansari (12IEEM14) Ali Arslan Pathan (12IEEM28)
  2. 2. PHOSPHORUS CYCLE• The phosphorus cycle is the biogeochemical cycle that describes the movement of phosphorus through the lithosphere, hydrosphere, and biosphere.
  3. 3. The Cycle The phosphorus cycle is long and slow, but it is an important part of the environment. It helps plants grow, and is used by farmers to fertilize them. When animals eat the plants, they absorb phosphates.
  4. 4. The Cycle (continue) Phosphates move quickly through plants and animals; however, the processes that move them through the soil or ocean are very slow, making the phosphorus cycle overall one of the slowest biogeochemical cycles.
  5. 5. When the animals die, theirbody decays and thephosphorus is absorbed intothe soil, where it re-entersplants.What isn’t absorbed by plantsends up in rock, and may staythere for millions of years,slowly being released as therocks weather.
  6. 6. AtmosphereThe Phosphorus cycle has noinvolvement in the atmosphere,because it does not naturallyform in gaseous forms.
  7. 7. Hydrosphere Phosphorous usually enters the hydrosphere by the phosphate salt rocks found on the ocean floor. As the water erodes them away, the phosphorous escapes. Marine organisms take some of the phosphorus particles in order to live and grow.
  8. 8. Lithosphere Phosphorous is presented in the form of rocks and soil. Phosphates go down to the bottom of the ocean and forms rocks over million of years. Phosphates enters the soil when plant and animal matter decompose, the cycle repeats.
  9. 9. Biosphere Phosphorous is used for organisms to build DNA(Deoxyribonucleic acid), RNA(Ribonucleic acid), and ATP(Adenosine-triphosphate).
  10. 10. Biosphere (continue) Phosphate is in plants, which the herbivores eat, which the herbivores are eaten by the carnivores. Than phosphorus is released back into the soil by the herbivores and carnivores waste.
  11. 11. Human Inputs to thePhosphorus Cycle Human influences on the phosphate cycle come mainly from the introduction and use of commercial synthetic fertilizers.
