What does aerobic decomposition involve?

Aerobic decomposition primarily refers to the process where organic waste is broken down by microorganisms in the presence of oxygen. This process is a key component of composting and contributes significantly to waste management practices. During aerobic decomposition, bacteria and other microorganisms utilize oxygen to break down organic matter into simpler compounds, resulting in the production of carbon dioxide, water, and nutrients. This method is generally more efficient than anaerobic decomposition, as it often occurs at a faster rate and produces fewer offensive odors.

The other options do not accurately describe aerobic decomposition. For instance, degradation in the absence of moisture does not align with the necessity for moisture present in most decomposition processes, including aerobic decomposition. Similarly, stating that degradation occurs without microorganisms overlooks the fact that microorganisms are essential for the breakdown of organic material in aerobic conditions. Finally, degradation of inorganic materials does not pertain to aerobic metabolism, as aerobic decomposition specifically refers to organic waste processing. The key characteristic of aerobic decomposition is its reliance on oxygen, making it the correct answer.
