The carbon cycle models the movement and storage of carbon in the biosphere, lithosphere, hydrosphere and atmosphere. Carbon is stored in the biosphere as living organisms; in the atmosphere as carbon dioxide gas; in the lithosphere as soil organic matter, as fossil fuel deposits, and as sedimentary rock deposits; and in the oceans as dissolved carbon dioxide gas and as calcium carbonate shells in marine organisms. Processes that move carbon from one store to another include photosynthesis, respiration, oceanic diffusion, biomass combustion, fossil fuel burning, fossil fuel creation, and sedimentary rock formation.  4, record 3, English, - carbon%20cycle

Ciclo del carbono. El carbono es elemento básico en la formación de las moléculas de carbohidratos, lípidos, proteínas y ácidos nucleicos, pues todas las moléculas orgánicas están formadas por cadenas de carbonos enlazados entre sí. La reserva fundamental de carbono, en moléculas de CO₂ que los seres vivos puedan asimilar, es la atmósfera y la hidrosfera. Este gas está en la atmósfera en una concentración de más del 0, 03% y cada año aproximadamente un 5% de estas reservas de CO₂, se consumen en los procesos de fotosíntesis, es decir que todo el anhídrido carbónico se renueva en la atmósfera cada 20 años.  3, record 3, Spanish, - ciclo%20del%20carbono

The second stage in the process of phtosynthesis is called the Calvin Cycle (it is also called the Calvin-Benson Cycle or the Carbon Fixation Cycle). In the Calvin Cycle, carbon molecules from carbon dioxide, CO₂, are fixed into the sugar glucose, (C₆H₁₂O₂) (in six repeats of the cycle). The Calvin Cycle takes place in the stroma of eucaryotic chloroplasts. The major enzyme that mediates the Calvin Cycle is Rubisco (ribulose-1-5-biphosphate carboxylase). The Calvin Cycle was first investigated in the late 1940s and early 1950s by the Nobel Prize winning chemist Melvin Calvin (1911-1997).  6, record 4, English, - Calvin%20cycle

All photosynthetic plants take carbon dioxide from the atmosphere and convert it, through a complicated sequence of chemical reactions, into starches and sugars. In C3 plants all the cells in the mesophyll of a leaf conduct photosynthesis by the same process, a sequence of reactions called the Calvin cycle. Early in the cycle, atmospheric carbon dioxide is incorporated, or fixed, into a compound containing three carbon atoms.  8, record 4, English, - Calvin%20cycle

Calvin-Benson Cycle (C3 cycle). So named because some of the important molecules in the cycle have 3 carbons in them.
