2.  In oceans  Air  Soil  And ALL LIVING THINGS:organic  Sugar, Coal and Diamond

3.  CO 2 is the gas that adds the sun going through photosynthesis.  The CO2 is pulled from the air and converted to C for plant food.

4.  in the Food chain the Carbon is moved from animals that eat plants (herbivores) and animals that consume them (carnivores).

5.  When plants and animals dies their bodies wood and decay bringing C- Carbon in the ground.

7. EXHALE  Breathe in Oxygen  Exhale Carbon Dioxide  This process is called RESPIRATION

8.  Human burn fossil fuels to Heat.  This heat enters the atmosphere as carbon dioxide  EACH YEAR ½ million tons (100 million elephants) of C is released to atmosphere by fossil fuels then to our seawater

9.  The oceans and other bodies of water soak up C0 2

10.  Carbon is a greenhouse gas, which keeps the earth warm.  Too much C causes the earth to become too hot and the planet becoming warmer.

13.  Nitrogen-fixation Atmospheric: Nitrogen (N2) is oxidized at high temperatures (by lightning, in internal combustion engines) to make nitrite (NO2) (which is deposited throughout the atomsphere) 

14.  Conversion to Ammonia. As amino acids and nucleic acids require N in the form of Ammonia, if nitrate (NO3) present, it must be converted to NH3.

15.  Step 3: Biological Use. Ammonia is incorporated into proteins, nucleic acids

16.  Step 4: When organism dies, ammonia is released back into the biosphere through the process of Ammonification, in which water is added to proteins to make carbon dioxide and ammonia.

17.  Step 5: If ammonia released into oxygen rich (anerobic) soil, other bacteria can convert it into nitrite or nitrate through the process of Nitrification: NH4+ + 2O2 = NO3- + H2O + 2H.

18.  atmospheric N2 through the process of Denitrification. In this process, bacteria use nitrate as an Oxygen source for respiration: C6H12O6 + 4NO3- = 6CO2 + 6H2O +
