Which microorganisms break down organic matter?

Which microorganisms break down organic matter?

• A. Decomposing Bacteria
• B. Heavy Metals
• C. Fracking
• D. Dissolved Oxygen Levels

Answer: (A)

Microorganisms that break down organic matter are decomposers, with bacteria playing a central role. Decomposing bacteria use enzymes to hydrolyze and oxidize complex organic compounds, converting them into simpler substances like carbon dioxide, water, ammonium, and nitrate. This process recycles nutrients and is essential in soils, sediments, and wastewater treatment, where organic waste is continuously broken down by microbial activity. Heavy metals are inorganic elements that do not biodegrade; they can persist and accumulate in the environment, sometimes becoming toxic. Fracking is a method for extracting fossil fuels, not a biological process. Dissolved oxygen levels describe how much oxygen is in water, which affects how fast decomposition occurs, but they are not microorganisms themselves. So, the best answer points to decomposing bacteria as the organisms responsible for breaking down organic matter, reflecting their key role in biodegradation and nutrient cycling.
