Answers
It is a cycle involving biological, geological, and chemical processes in which carbon atoms are exchanged between the Earth's biosphere, pedosphere, geosphere, hydrosphere, and the atmosphere. Carbon cycle is one of the most important cycles of the Earth and symbolizes the recycling of this abundant element throughout the biosphere as well as in all of its organisms.
It is usually considered that there are five major reservoirs of carbon on the planet, which are interlinked by flow of exchanges. These reservoirs are:
The atmosphere
The terrestrial biosphere, which includes freshwater sources and other organic material like soil carbon.
The oceans―contain dissolved carbon in inorganic as well as organic, living and non-living, and marine flora and fauna.
The sediments, which includes fossil fuels.
The planet's interior has carbon in the Earth's mantle and crust. It is vented to the atmosphere or hydrosphere by volcanic eruptions and geothermal activities.
Explanation:
The carbon cycle is the process in which carbon travels from the atmosphere into organisms and the Earth and then back into the atmosphere. Plants take carbon dioxide from the air and use it to make food. Animals then eat the food and carbon is stored in their bodies or released as CO2 through respiration
