The carbon cycle is the movement of the carbon through the rock and sediment, the aquatic environment, land environments, and the atmosphere (including living organisms in all that).
Carbon is released from the plant into the atmosphere through the process of respiration in the form of carbon dioxide (CO2). Respiration is the process which is the reverse of photosynthesis. During respiration, the O2, taken in through stomata is used by the cells in the leaves to break down glucose into CO2 and H2O. The other way of releasing carbon from the plant into the atmosphere is by decomposition. Carbon can be stored as biomass in the roots of trees for many decades and then released back into the atmosphere by decomposition. Sometimes, dead plant matter accumulates faster than it is decomposed and the remains stay in underground deposits. When layers of sediment compress this matte,r fossil fuels will be formed and the carbon within those fossil fuels will be released during humane combustion processes.
Carbon is an important constituent of every living organism. The carbon cycle is the movement of carbon through sediment, water, and air to fulfill the requirement. The two ways in which carbon can get from a land plant to the atmosphere are cellular respiration and decomposition.
Carbon cycle is a biogeochemical cycle in which carbon is exchanged among hydrosphere, atmosphere, biosphere, and geosphere of the Earth. The two ways in which carbon can get from a land plant to the atmosphere are:
- Cellular Respiration is the process in which glucose in the presence of oxygen is broken down to yield energy and evolve carbon dioxide. The carbon in the form of oxide is directly released in the atmosphere continuing the cycle.
- Decomposition is the process in which dead and decaying substances are broken down into simpler forms. When the land plants are dead and decomposed in the soil, it releases carbon. The carbon is stored as biomass in the roots of trees and other plants. Thus, when these plants are accumulated in the sedimentary layers, it gets converted into fossil fuels.
- The combustion of fossil fuels releases carbon into the atmosphere.
Therefore, respiration, decomposition, and combustion are some of the process through which carbon is exchanged between different systems of Earth.
