Atmospheric carbon dioxide is the main source of carbon. Green plants store this carbon during the process of photosynthesis. Carbon dioxide supplies the carbon needed for all the organic matter.
nbnb
No, carbon dioxide is not a source of nitrogen or any nitrogen related compounds, because it consists of only (2 atoms of) Oxygen and (1 atom of) Carbon.
Volcanos release sulfur dioxide, carbon dioxide, and ash to the atmosphere at the same time
Burning any of the fossil fuels (coal, oil and natural gas) releases carbon dioxide.
As they provide a natural source of oxygen for the planet meanwhile they absorb carbon dioxide
The Carbon source for photosynthesis is the air
carbon dioxide
Any fossil fuels, hydrocarbons like coal, oil and natural gas, release carbon dioxide and water when burned.
carbon dioxide
Hydroelectricity is better because it releases no carbon dioxide emissions to cause global warming. Natural gas is the cleanest of the fossil fuels (coal, oil and natural gas), but it is still responsible for carbon dioxide (CO2) emissions.
water
Carbon dioxide is the source of carbon. It is reduced to glucose
CO2 is the source of carbon.
