In ecosystems, the carbon cycle is important because it transfers carbon, a life-sustaining factor, through species from the atmosphere and oceans and back to the atmosphere and oceans again. The carbon cycle is the manner in which nature reuses carbon atoms that migrate from the atmosphere into the Earth’s species and then back into the atmosphere over and over again. The role of decomposers is to eat the dead organism and return the carbon from their body back into the atmosphere. In the interiors of stars on the horizontal branch, carbon is created, according to the latest theory of physical cosmology. Photosynthesis by green plants takes their energy from the sun in order to break down water into oxygen and hydrogen. Carbon dioxide (CO2) a form of carbon is an essential element present in the air and in the water for sustaining life on earth.

Carbon can bind to, and to other carbon molecules, four other groups around it. Some of the carbon that is not released back into the atmosphere eventually become fossil fuels. For Example- Graphite is opaque, and diamond is transparent. These animals and plants eventually die, and upon decomposing, carbon is released back into the atmosphere. It is the 15th most abundant element in the Earth’s crust and 4th most abundant element after hydrogen, helium, and oxygen. So, carbon can form bond by sharing of its electrons with the electrons of other carbon atom or with other element and attain noble gas configuration. Carbon cycle explains the movement of carbon between the earth’s biosphere, geosphere, hydrosphere and atmosphere. Continue learning about the element carbon and its different forms with charts and interesting video lectures @BYJU’S. Ecologically, oceans take in more carbon than it gives out. Ionization Energies: Decreases from C to Sn and then increases up to Pb. Carbon-12 atom is taken to be the standard.The atomic masses of all other elements are determined by comparing the mass of their atom with the mass of a carbon-12 atom. Carbon is the most common chemical element which has the symbol C and atomic number 6. Photosynthesis by green plants takes their energy from the sun in order to break down water into oxygen and hydrogen. It is versatile non-metal. Carbon Cycle is a biogeochemical cycle where various carbon compounds are interchanged among the various layers of the earth, namely, the biosphere, geosphere, pedosphere, hydrosphere and atmosphere. It has 3 naturally occurring isotopes( 12C and 13C – stable, 14C – radioactive), It has several allotropes and best known are. Carbon forms covalent bond. Carbon enters the atmosphere through natural processes such as respiration and industrial applications such as burning fossil fuels. 3. Also learn the various elements of the carbon cycle diagram.
