Carbon and Nitrogen Cycle Carbon is an element

Carbon and Nitrogen Cycle

Carbon ©is an element … In oceans Air Soil And ALL LIVING THINGS: organic Sugar, Coal and Diamond

Carbon moves through the atmosphere to plants is the gas that adds the sun going through photosynthesis. The CO 2 is pulled from the air and converted to C for plant food. CO 2

Carbon moves from plant to animals… in the Food chain the Carbon is moved from animals that eat plants (herbivores) and animals that consume them (carnivores).

Carbon moves from plants/animals to the ground When plants and animals dies their bodies wood and decay bringing CCarbon in the ground.

The buried carbon becomes FOSSIL FUEL

Carbon moves from living things through the atomsphere. . EXHALE Breathe in Oxygen Exhale Carbon Dioxide This process is called RESPIRATION

Carbon moves from fossil fuel to atmosphere when fuel is burned 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

Carbon moves from the atmosphere to the Ocean The oceans and other bodies of water soak up C 02

Greenhouse Gas 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 Cycle

Example Fish. . they need Nitrogen

1. Nitrogen-fixation Atmospheric: Nitrogen (N 2) is oxidized at high temperatures (by lightning, in internal combustion engines) to make nitrite (NO 2) (which is deposited throughout the atomsphere)

2. Conversion of Ammonia Conversion to Ammonia. As amino acids and nucleic acids require N in the form of Ammonia, if nitrate (NO 3) present, it must be converted to NH 3.

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

4. Organism dies… 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.

5. Bacteria to Nitrite Step 5: If ammonia released into oxygen rich (anerobic) soil, other bacteria can convert it into nitrite or nitrate through the process of Nitrification: NH 4+ + 2 O 2 = NO 3 - + H 2 O + 2 H.

6. Nitrate as an Oxygen source atmospheric N 2 through the process of Denitrification. In this process, bacteria use nitrate as an Oxygen source for respiration: C 6 H 12 O 6 + 4 NO 3 - = 6 CO 2 + 6 H 2 O +
