In oceans Air Soil And ALL LIVING THINGS:organic Sugar, Coal and Diamond
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.
in the Food chain the Carbon is moved from animals that eat plants (herbivores) and animals that consume them (carnivores).
When plants and animals dies their bodies wood and decay bringing C- Carbon in the ground.
EXHALE Breathe in Oxygen Exhale Carbon Dioxide This process is called RESPIRATION
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
The oceans and other bodies of water soak up C0 2
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.
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)
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.
Step 3: Biological Use. Ammonia is incorporated into proteins, nucleic acids
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.
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.
atmospheric N2 through the process of Denitrification. In this process, bacteria use nitrate as an Oxygen source for respiration: C6H12O6 + 4NO3- = 6CO2 + 6H2O +
