What greenhouse gas is produced from aerobic decomposition?

During aerobic decomposition, organic matter is broken down by microorganisms in the presence of oxygen. This process primarily produces carbon dioxide (CO2) as a byproduct. The aerobic decomposition utilizes oxygen, which leads to the complete oxidation of carbon-containing substances in the organic material. As the microorganisms metabolize this organic matter, they convert it into energy, releasing carbon dioxide into the atmosphere.

The production of carbon dioxide in this process is significant because it contributes to the greenhouse gas effect. Carbon dioxide is a key factor in climate change, as it traps heat in the atmosphere. This makes understanding the processes that lead to its emission critical for environmental management and policy-making.

In contrast, the other substances listed—ammonia, methane, and hydrogen—arise from different processes or conditions. Ammonia typically results from the breakdown of nitrogenous compounds in a more anaerobic or neutral environment, methane is produced in anaerobic decomposition, and hydrogen is less commonly associated with organic degradation in typical biological contexts.
