Presentation Transcript

  1. Phosphorus Cycle http://en.wikipedia.org/wiki/Phosphorus Element: S.BIO.6.1.b Ecosystems: Matter/Energy FlowThe learner will explain the flow of matter and energy through ecosystems by: • Arranging components of a food chain according to energy flow.• Comparing the quantity of energy in the steps of an energy pyramid.• Explaining the need for cycling of major nutrients (C, O, H, N, P).

  2. Phosphorus in the Animal Kingdom • Required in every cell in the human body • Most phosphorus is in the form of phosphate PO4 • 85% of the phosphorus in the body is in bone in the form of Calcium Phosphate • Cell membranes have the phospholipid bi-layer • DNA and RNA have phosphate as one of the three components of the nucleotide http://publications.nigms.nih.gov/thenewgenetics/images/ch1_nucleotide.jpg http://www.biologycorner.com/resources/lipidbilayer.gif

  3. Remember • All living things are made up of cells (The Cell Theory) • DNA is found in all cells as the genetic material • Creatine phosphate contains phosphorus and allows the cell to utilize energy • ATP has three phosphate groups and powers cells http://leavingbio.net/ENERGY%20FOR%20LIFE_files/image002.gif

  4. Phosphorus https://bioh.wikispaces.com/file/view/36-17-PhosphorusCycle-L.gif/31445793/36-17-PhosphorusCycle-L.gif • Phosphorus is strange in that it does not enter the atmosphere whereas carbon, nitrogen and oxygen do cycle through the atmosphere in the gaseous state.

  5. Phosphorus Cycle • Phosphate is often mined from sedimentary rock or collected from guano • It is added to crops as a fertilizer or added to animal feed as a supplement • Once in the producers, phosphate cycles through the food web although it never exists in the gaseous state http://www.lesco.com/images/roots_flat.jpg http://www.lesco.com/images/roots_flat.jpg
