Which of the Following Does Not Contribute to the Increasing

Question

Which of the following does not contribute to the increasing levels of methane in the atmosphere?
A)Methane production in termites
B)Methane production in rice paddies
C)Methane production at sewage treatment plants
D)Methane production beneath an aerobic water column

Accepted Answer

Methane production beneath an aerobic water column is not a significant contributor to increasing levels of methane in the atmosphere because aerobic conditions do not support methane production. Methane is produced under anaerobic conditions, which occur in the other three options (termites, rice paddies, and sewage treatment plants).
