Before I answer this question please reword it so it is understandable.
photosynthesis
Carbon dioxide is a gas that can be changed to a solid. When turned to a solid carbon dioxide becomes dry ice.
Hi, Carbon dioxide can be changed into liquid,this liquid is commonly called as dry ice.
Oxygen and carbon dioxide change in the lungs.
Desublimation
fermentation
Carbon atoms from a complex organic food molecule, such as glucose, are completely oxidized at the end of its reaction chain. Carbon dioxide is the waste that is released as a result of this reaction.
Not much, avaliability is the same also. Our default has changed to killed carbon steel.
Carbon dioxide is increasing in the atmosphere, and oxygen is decreasing.
i
Because carbon cannot be changed into a simpler substance by normal means
Because the atmospheric CO2 concentration is part of the "Carbon Cycle" and biological and geological processes therefore affect it.
