Answer:
The carbon dioxide level is increasing because the trees in those forests used to take the carbon dioxide for photosynthesis.
Explanation:
Here this is what I found:)
An inference, because its an educated guess based on context
Anaerobic condition refers to an environmental condition where oxygen is absent. In case of Electron Transport System (ETS) and ATP production, oxygen acts as the final acceptor of electrons. As oxygen is a reactant in ETS and ATP production, unavailability of oxygen can cause no oxidation of the coenzymes or the carriers such as NAPH and FADH2 and no ATP will be produced. Thus, both Electron Transport System and ATP production will stop in the absence of oxygen.
