The only carbon dioxide released by simply cutting the tree is that which is produced by the energy required to cut the tree: the human breathing out carbon dioxide as he swings an axe or uses a saw, the carbon dioxide emitted by a chainsaw's combustion engine, or the carbon dioxide emitted by logging machinery while cutting the tree.
Significantly more carbon is emitted afterward as the lumber is transported from the site and as the tree is cut up into smaller pieces, then the smaller pieces are shipped all over. Finally, as the wood biodegrades (or burns), some carbon dioxide will be released.
carbon dioxide :p
Carbon Dioxide is Used during Photosynthesis, and Oxygen is released after the process.
Carbon dioxide
carbon dioxide
Carbon dioxide is released during the light reaction.
photosynthesis
Carbon dioxide is released during the light reaction.
The energy released during respiration is in the form of adenosine triphosphate (ATP). This energy is produced through the breakdown of glucose within cells, which is used to fuel various cellular processes and activities.
Aerobic respiration Glucose + Oxygen = Water + Carbon dioxide
Carbon dioxide is produced during the process of cellular respiration During cellular respiration energy is released in the form of ATP. Oxygen is reduced to form water and Carbon of glucose combines with oxygen to produce carbon dioxide. Thus, carbon dioxide, water and energy are produced during cellular respiration.
carbon dioxide
When you exhale, carbon dioxide is released into the atmosphere.
