Answer:
Carbon dioxide (CO2) is an important component in atmosphere and Carbon cycles allows movement of carbon dioxide from the atmosphere into living things and from living things to atmosphere again.
There are four main processes included in carbon cycle that is photosynthesis, decomposition, respiration and combustion.
In respiration, living organism such as animals and humans intake oxygen and releases CO2 in atmosphere.
In the process of photosynthesis, plants take CO2 from atmosphere and convert it into oxygen (O2) in the presence of sunlight and water.
In Decompoition, the bacteria present in soil decomposes dead matter by breaking down into simpler organic or inorganic matter such as water, carbon dioxide, and mineral salt. The nutrient cycle then recycle the carbon dioxide and send back to teh atmosphere.
In combustion, the burning of fossil fuel in cars and industries releases carbon dioxide back into the atmosphere.
So, the components of carbon cycel include atmosphere, terrestial biosphere, ocean ( dissolved inorganic carbon), and sediments ( fossil fuels).
