Which term describes the decomposition of organic matter in the absence of oxygen?

• A. Aerobic
• B. Anaerobic
• C. Ambient
• D. Auxiliary

Answer: (B)

The term that describes the decomposition of organic matter in the absence of oxygen is anaerobic. During anaerobic decomposition, microorganisms break down organic materials without the use of oxygen. This process often occurs in environments where oxygen is limited, such as deep in soil, swamps, or in the stomachs of certain animals. Anaerobic decomposition is crucial in natural ecosystems as it allows for the recycling of nutrients and the breakdown of organic waste. Additionally, this process can produce methane and other gases, which can be harnessed for energy in anaerobic digestion facilities designed to manage waste. The other terms relate to different processes. For instance, aerobic refers to decomposition that occurs with oxygen, while ambient describes environmental conditions that are generally surrounding or prevailing but not directly linked to decomposition processes. Auxiliary refers to something that provides additional support or assistance, which is not relevant in this context.
