Presentation Transcript

  1. Cycles

  2. Water Cycle

  3. Water Cycle • Evaporation • Water changing into gas • Happens on the surface of a liquid • Transpiration • Water changing into gas • Happens from leaves of plants • Condensation • Gas changing into liquid • Precipitation • Water fallingfrom clouds

  4. Water Cycle • Runoff • Water running down surface to river/stream • Seepage • Water going into soil • Root Uptake • Water entering plants through roots

  5. Carbon Cycle

  6. Carbon Cycle LAND • Photosynthesis • Carbon becomes carbohydrates (ORGANIC) • Feeding • Animals digest carbohydrates • Respiration & Human Activity • Release CO2 into atmosphere • Carbon becomes INORGANIC • Decomposition • Dead animals decompose • Deposition • Build up of organic matter • Fossil Fuels • Burned by humans

  7. Carbon Cycle OCEAN • Photosynthesis • Carbon becomes carbonate (ORGANIC) • Feeding • Animals digest carbonates • Respiration & Erosion • Release CO2 back into atmosphere through ocean • Deposition • Carbonates build up on ocean floor • Uplift • Earth movement releases CO2 gases • Volcanic Activity • Releases CO2 into atmosphere • Carbon becomes INORGANIC

  8. Nitrogen Cycle

  9. Nitrogen Cycle • Synthetic Fertilizer Manufacture • Nitrogen gas used to make fertilizer • Uptake by Producers • Take in nitrogen to produce proteins • Use nitrates/nitrites to make proteins • Reuse by Consumers • Reuse nitrogen from producers

  10. Nitrogen Cycle • Decomposition/Deposition and Excretion • Dead animals/waste converted to ammonia (NH3) • Bacterial Nitrogen Fixation • Bacteria convert nitrogen into ammonia (NH3) • Atmospheric Nitrogen Fixation • Atmosphere converts nitrogen into nitrates/nitrites • Denitrification • Bacteria converts NO3/NO2 into nitrogen gas • NH3 converted into Nitrates/Nitrites (NO3/NO2) by bacteria in soil
