Question
Under which of the following conditions would a tree add biomass and grow?Over time, a tree releases more carbon back to the air via respiration than it takes in via photosynthesis.Over time, a tree takes in more carbon via photosynthesis than it releases back to the air via respiration.Over time, a tree takes in the same amount of carbon via photosynthesis as it releases back to the air via respiration.
Solution
A tree would add biomass and grow under the condition where, over time, a tree takes in more carbon via photosynthesis than it releases back to the air via respiration.
Here's why:
-
Photosynthesis is the process by which green plants, including trees, use sunlight to synthesize foods with the help of carbon dioxide and water. In this process, trees absorb carbon dioxide from the air.
-
Respiration is the process by which trees release carbon dioxide back into the air.
-
If a tree is taking in more carbon via photosynthesis than it is releasing via respiration, it means that there is a net gain of carbon in the tree.
-
This net gain of carbon contributes to the tree's biomass, leading to growth.
