Carbon Cycle







The Carbon Cycle

















Carbon Cycles is one of the most important for the Erhart's stability and maintenance. It is found in the atmosphere, on vegetation, the ocean , and beneath the earths ground also as known fossil fuels.

In the atmosphere carbon coexist as a gas (CO2) but in smaller amounts (approx .04% on a molar basis, and basis). It plays an important rule of maintaining life. Other carbon gasses are found such methane, and chlorofluorocarbons. These two previous mention gases are also called green gases and they are growing in large quantities creating the issue of global warming. Carbon is taken from the atmosphere in different ways.

As the sun shines the plants convert the carbon into oxygen thanks to the photosynthesis creating carbohydrates realising the oxygen into the air.
Forest hold 86% on the earth's carbon-atmosphere, and 73% of the planet's soil carbon.

Carbon is released in many ways; the respiration made by plants and animals, through decay, by fungi and bacteria break down, through combustion, fossil fuels such; petroleum, natural gas, production of cement when heating limestone carbon is released and create lime a component of cement, and by volcanic eruptions, water vapors and sulfur dioxide.

In the Biosphere Autotrophs produce their own organic compounds using CO2 from air or water in which they live. To perform these task they would need an source of energy, generally all Autotrophs get the energy from the sun and this process is call photosynthesis. On land the process is made by trees and in water by phytoplankton.

In the Ocean the presence of carbon is about 36,000 gigatones manly bicarbonate ion.
Extreme storms such hurrinaces and typhoons bury a lot of carbon because they wash away the sediment. A study made in Taiwan conclude that a single typhoon can collect large quantities of carbon , more that the single rains that can happen in that country combine in one year.

Inorganic carbons also play an important role when they are combine with carbon-carbon or carbon-hydrogen bonds. this carbon exchange is crucial for determine the PH of the oceans water.

Carbon is essential for our environment but it can be dangerous if not properly managed. All organinc and inorganic species relay on carbon for their existance, as human kind it is necesary to controll their usage and disposal.
