Reservoir, flux and source of carbon cycle schematic diagram
Between heaven and earth, the cycle of carbon is related to the survival of all things. Today, I will describe the outline of the reservoir, flux and source of carbon cycle schematic diagram.

First, the storage
The storage of carbon is widely distributed. One is the atmosphere, although the amount of carbon in it is not huge compared with other places, it is closely related to the global climate. Carbon dioxide floats in the middle, like threads, affecting the heat budget and climate change. The second is the ocean, the vast ocean, with countless carbon deposits. The dissolved carbon in seawater, either precipitated by biological action or recycled with ocean currents, maintains the marine ecological carbon balance, and is also a key link in the global carbon cycle. Another is the terrestrial ecosystem, forests, grasslands, and soils, all of which are carbon reservoirs. Forests are lush, sequestering carbon through photosynthesis, such as green guards; soils contain animal and plant residues, accumulating organic carbon, and silently guarding the terrestrial carbon pool.

Second, flux
The flux of carbon is the rate at which carbon is transferred between reservoirs. Photosynthesis is an important flux for terrestrial and marine ecosystems to absorb atmospheric carbon. Green plants use the power of sunlight to convert carbon dioxide into organic matter, fixing carbon elements, such as clever hand brocade, to add luster to the ecology. On the contrary, the biological body releases carbon into carbon dioxide and returns it to the atmosphere, just like the rhythm of life, breathing new things. In addition, the combustion of fossil fuels has an amazing flux. Humans use coal, oil, and natural gas to release carbon buried deep in the ground at a rate far exceeding natural processes, such as floods bursting levees, impacting the balance of the original carbon cycle, and causing climate changes.

Third, the sources
The sources of carbon are diverse and complex. In natural sources, volcanoes erupt and ground fires surge, carrying underground carbon to the surface and atmosphere, although not daily, but energy is huge. Biological respiration and decomposition are also common carbon sources. Organisms survive and metabolize, exhaling carbon dioxide; animal and plant remains decay, and carbon returns to the environment. Anthropogenic sources are especially fossil fuel combustion. Industrial development and smooth transportation all rely on fossil energy, and their combustion emits huge amounts of carbon, which has become the main cause of contemporary carbon cycle disturbance. Land use change, such as deforestation, destroys the carbon sequestration mechanism and releases carbon storage, which is also one of the carbon sources, affecting the ecology and climate.

The cycle of carbon is like a ring without reason. Reserves, fluxes and sources are intertwined, which affects the whole body. Only by understanding its reason can we understand the delicacy of ecology, so as to seek a harmonious coexistence between man and nature.
