  1. Chemicals cycle in ecosystems By: Paul Kennedy and Stephanie Bradley

  2. Chemical cycling

  3. they are:  oxygen cycle Carbon cycle Nitrogen cycle water cycle Each cycle a certain element Each essential to balance elements on earth The 4 main cycles

  4. Photosynthesis/Oxygen cycle • Oxygen is cycled through plants/trees •  6CO2 + 6H2O + ENERGY > C6H12O6 + 6O2 • Plants take carbon dioxide from air • give back oxygen

  5. Respiration/Oxygen cycle • Takes oxygen from air or water •  Animals/plants take oxygen from air • They give back carbon dioxide

  6. The Carbon cycle • There are two types of the carbon cycle • The Aquatic carbon cycle • And the terrestial carbon cycle •  carbon is used by producers, consumers, and decomposers • Cycles rapidly through air, water, and biota • Biota is all plant/animal life in one area

  7. The Aquatic and Terrestrial carbon cycle

  8. The Nitrogen cycle • It moves between the atmoshpere, biosphere, and geosphere • There are 5 processes in this cycle • They are - •  Nitrogen fixation •  Nitrogen uptake (organismal growth) •  nitrogen decay •  nitrification •  denitrification

  9. Water cycle • The main processes for it are - •  evaporation •  condensation • precipitation • collection
