Trees predominantly release which type of gases at night?

Trees, generally, release the same gases that we do, during night. In other words, trees release carbon dioxide at night, just like human beings and other animals do throughout our life. This carbon dioxide is a result of cellular respiration taking place within the plant at night. Chemically, we can represent cellular respiration as:


`C_6H_12O_6 + 6 O_2 -> 6 CO_2 + 6 H_2O + ATP`


In this reaction, glucose molecules are broken down, in...

Trees, generally, release the same gases that we do, during night. In other words, trees release carbon dioxide at night, just like human beings and other animals do throughout our life. This carbon dioxide is a result of cellular respiration taking place within the plant at night. Chemically, we can represent cellular respiration as:


`C_6H_12O_6 + 6 O_2 -> 6 CO_2 + 6 H_2O + ATP`


In this reaction, glucose molecules are broken down, in presence of oxygen, and carbon dioxide and water are generated, along with ATP molecules. This process provides energy to the trees and plants. It is the products of this process, that plants and trees release at night.


Interestingly, this process continues throughout the life of plants, yet we do not see much effect during daytime, since photosynthesis is taking place and is consuming these products (of cellular respiration) as reactants. 


Hope this helps.
