Atmospheric Carbon
Our atmosphere holds many gases. Among these is carbon. Ecosystems receive most of their carbon from the atmosphere. This is one of the reason for global warming, hints carbon dioxides nickname "the greenhouse gas."

The Carbon Cycle
The Earths atmosphere contains 0.035% carbon dioxide. The earth contain so little,but it is relied on for this planet to function and survive. The environment relies on carbon to to pull proteins, sugars, and fats out of plants. Carbon is also relied on to be a reactant in the production of oxygen. Through the tropic system carbon also plays a big role. Herbivores eat plant and in turn the herbivores are eaten by carnivores.
Carbon is used in the process of many things. But you may be wondering how it gets back to the environment? Animals play a huge part in this, in the sense that animals absorb oxygen but exhale carbon dioxide. Dead organisms also have a part in getting CO2 back into the environment due to that during fossilization some carbon returns to the physical environment.

Photosynthesis and Cellular Respiration
You will find carbon throughout the process of photosynthesis and cellular respiration. Each of these processes has its own equation, like you see below. In photosynthesis carbon dioxide is a reactant along with water while the product is oxygen and glucose. Therefore carbon plays a huge role in the creation and function of photosynthesis.
Cellular respiration is the opposite of photosynthesis. Therefore the reactants of cellular respiration are oxygen and glucose while the products are carbon dioxide and water. To convert glucose to carbon dioxide two things must occur 1.) aerobic respiration and 2.)glycolysis.
CELLULAR RESPIRATION EQUATION: C6H12O6 + 6O2 ----> 6CO2 + 6H2O + Energy
PHOTOSYNTHESIS EQUATION: 6CO2+ 6H2O ----> C6H12O6+ 6O2

Bonding Patterns of Carbon
Atomic Structure
Carbon starts out as just a simple element found on the periodic table. It symbol is C and it's atomic number is 6. Its atomic structure has to do with a lot of the processes and things that carbon is involved in. Carbon has two energy levels, the first energy level consists of two electrons and the second energy level consists of four.
