1 Nutrient Cycles Notes

2 Water Cycle Condensation - when tiny droplets of water form clouds
Precipitation - when water is returned to the ground (rain, sleet, snow, hail) Evaporation - when water changes from liquid form to an atmospheric gas Biological Transpiration - when water is released from the leaves of plants into the atmosphere Root Uptake – when plants absorb water from the ground


4 The Water Cycle The Water Cycle Section 3-3 Condensation Precipitation
Evaporation Transpiration Runoff Seepage Root Uptake

5 Nitrogen Cycle Nitrogen Fixation
Bacteria have a symbiotic relationship with plants. They can take Nitrogen from non-living sources and convert it into usable form for living organisms. Nitrogen is passed through the food chain Denitrification when other bacteria in the soil convert nitrates into nitrogen gas


7 Nitrogen Cycle N2 in Atmosphere NO3- and NO2- NH3

8 Carbon Cycle Photosynthesis Respiration Decomposition
6CO2 + 6H2O -> C6H12O6 + 6O2 Carbon dioxide required Releases oxygen Respiration C6H12O6 + 6O2 -> 6CO2 + 6H2O Requires oxygen releases carbon dioxide Decomposition


10 CO2 in air Carbon Cycle CO2 in ocean
