During photosynthesis, plants absorb carbon dioxide and sunlight to create fuel—glucose and other sugars—for building plant structures. This process forms the foundation of the fast (biological) carbon cycle. ... In all four processes, the carbon dioxide released in the reaction usually ends up in the atmosphere.
I guess because of concentration.....it stops !
Carbon dioxide is used to build sugars. I think it's the only one
It controls all the involuntary actions like digestion and beating of our heart
