Essay on the Carbon Cycle (With Diagrams) | Ecosystem

The carbon cycle is very complicated as carbon is found in various kinds of compounds such as plants, animals, rocks, liquids, sediments and air.

The most important carbonaceous materials are CO2, CO, carbonate and organic carbonaceous materials. There is 0.03% CO2 gas in the atmosphere. A large amount of carbon material is carbon dioxide dissolved in fresh water and salt water.

They form carbonates or bicarbonates which deposit as sediments or as crustal deposits such as limestone and marble. However, green plants fix large amounts of carbon dioxide to organic carbon by photosynthesis in land and aquatic ecosystems.

Some of them are deposited as fossil fuels such as coal and petroleum. On the other hand, carbon dioxide is released into the atmosphere by fuel combustion, bio-population, volcanic and organic waste decomposition. FIG. 17 shows the overall view of the carbon cycle.

In some cases, carbon dioxide circulates very rapidly like plants that fix carbon dioxide by photosynthesis in one hour and may release carbon dioxide through the same rapid breathing.

However, abiotic processes or complex biological and abiotic processes result in the formation of carbonate rocks or fossil organic fuel deposits that take millions of years to produce. In the present age, human activities have great influence on the global carbon cycle.

When fossil fuels are burned, the geological reserves of carbon are converted to carbon dioxide and released into the atmosphere. Today, due to the combustion of fossil fuels and the destruction of forests, the release of carbon dioxide into the atmosphere or the release of carbon dioxide is steadily increasing. Figure 18 shows a simplified model of carbon flow in the environment.

Because global warming is occurring due to global carbon dioxide increase, especially global CO 2 increase over the past several decades, green effect is drawing attention. Figure 19 shows an overview of the global warming problem caused by turbulence in CO2 circulation.

Carbon cycle chart Black numbers indicate the amount of carbon stored in various reservoirs, billions of tons ("GtC" for carbon gigantons, figures around 2004). Purple numbers indicate the amount of carbon transfer between reservoirs every year. As shown, this deposit contains no carbonate rocks and kerogens of about 700,000 GtC. It is very rare to convert an element under ground conditions to another element. Therefore, the amount of carbon on the earth is actually constant. Therefore, in processes that use carbon, you need to get it from somewhere and destroy it elsewhere. The path of carbon in the environment forms a carbon cycle. For example, photosynthetic plants absorb carbon dioxide from the atmosphere (or sea water) and accumulate it in biomass, like the carbon fixation process of the Calvin cycle. Some of these biomass are eaten by animals, and some carbons are exhaled by animals as carbon dioxide.

Carbon is the foundation of all life on Earth. This article describes the role of carbon dioxide in various parts of the carbon cycle. In this article I will begin by explaining the ocean's role in carbon absorption and studying the two major and important parts of the carbon cycle. Next, in this article we will investigate human impact on carbon cycle and human carbon dioxide production. Thirdly, this article explains what controls the carbon dioxide concentration. The ocean contains a lot of carbon. Carbon dioxide in the atmosphere constantly enters and leaves the ocean and is balanced by dissolving in extremely cold water. Plankton also plays an important role in maintaining the carbon budget. Ocean plankton in the world uses carbon dioxide for growth (photosynthesis). Abandoned organic matter precipitates from these ecosystems and removes carbon and nutrients from the surface.

In ecosystems, substances and nutrients circulate biogeochemical cycles of water, carbon dioxide, nitrogen, phosphorus and so on. Combustion of fossil fuel contributes to the industrial cycle of atmospheric carbon dioxide. This contributes to the greenhouse effect which is the cause of global warming. Nitrogen is present in the atmosphere and accounts for about 78% of the Earth's air-fuel mixture. Oxygen accounts for about 22% of the Earth's air mixture and pollutants make up about 1% of the Earth's air mixture. Nitrogen is important for the development of creatures on the earth for the production of compounds such as proteins and amino acids. These compounds are important because they constitute DNA and other compounds indispensable for the formation and maintenance of life.
