An examination of the carbon budget of a pool or reservoir can provide information about whether the pool or reservoir is functioning as a source or sink for carbon dioxide. The global carbon budget is the balance of the exchanges (incomes and losses) of carbon between the carbon reservoirs or between one specific loop (e.g., atmosphere ↔ biosphere) of the carbon cycle. The ocean contains the largest active pool of carbon near the surface of the Earth, but the deep ocean part of this pool does not rapidly exchange with the atmosphere. Both factors have led to some additional plant growth. fossil fuel: Fossil fuels such as coal, petroleum products and natural gas are sources of ancient biomass that were formed millions of years ago from the decay of plant and animal matter. Carbon dioxide increases temperatures, extending the growing season and increasing humidity. carbon cycle: The carbon cycle can be described as the exchange of carbon between the land, the oceans, the atmosphere and the Earths interior. Sedimentary Cycle: the reservoir is the earth’s crust (soluble elements mostly found in earth’s crust. Collectively, all of the major pools and fluxes of carbon on Earth comprise what we refer to as the global carbon cycle. The biggest changes in the land carbon cycle are likely to come because of climate change. Gaseous Cycle: the reservoir is the atmosphere or the hydrosphere water cycle, carbon cycle, nitrogen cycle, etc. The annual movements of carbon, the carbon exchanges between reservoirs, occur because of various chemical, physical, geological, and biological processes. Based on the nature of the reservoir, a nutrient cycle is referred to as Gaseous or Sedimentary cycle. The carbon cycle is usually thought of as four major reservoirs of carbon interconnected by pathways of exchange. The carbon cycle is the biogeochemical cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth. Carbon is the major chemical constituent of most organic matter, from fossil fuels to the complex.
