Chapter 4 Importance of… Water Cycle Human consumption Fresh water is limited Electronic manufacture Sustain life on Earth Hydroelectric energy source Coolant for energy production Agriculture, food production Box and Arrow diagram: Storage basin (box) (_____) Transfer/process/action ( ) Ocean Evaporation (or Transpiration (plants)) Atmosphere Precipitation Surface water (or glaciers, ice caps, groundwater, aquifers, soil) Nitrogen Cycle (N2 makes up 78% of the atmosphere) DNA Protein (active proteins=enzymes) Plants need nitrogen, we need plants Food production o Fixation takes nitrogen from the atmosphere and makes it available to the biosphere o People have messed up the nitrogen cycle Atmosphere Nitrogen fixation(microorganisms) soil (Ammonia, Nitrate) plants producers, consumers Denitrification through microorganisms atmosphere Humans have figured out ways to double the nitrogen fixation

Unformatted text preview: Eutrophication (excess nitrogen in water sources) algae grows and decomposition uses lots of dissolved oxygen, lessening the availability of dissolved oxygen for consumers (fish) Carbon Cycle Climate Carbon in plants Fossil fuels (coal, natural gas, petroleum) Diamonds Biosphere (plants + consumers) Atmosphere (CO2, Methane) Photosynthesis (CO2 fixation in plants) Volcanic Activity ----------------Atmosphere Fossil Fuel burning into the. .Atmosphere Decomposition and Deforestation Atmosphere Ocean (Dissolved CO2, life) Atmosphere (through diffusion) CO2 is a greenhouse gas Too much CO2 increases the greenhouse effect which increased the temperature Example of Positive Feedback which is a negative outcome: CO2 raises temperature, ice melt reduce albedo (reflective energy from ice) increase temperature...
