What happens to organic matter during the stability phase?

• A. It increases nitrogen availability
• B. Microorganisms break it down
• C. It becomes entirely mineralized
• D. It enhances soil texture

Answer: (B)

During the stability phase, organic matter is primarily broken down by microorganisms. This process involves the decomposition of organic material by bacteria, fungi, and other decomposers, which play a crucial role in the cycling of nutrients within the ecosystem. As these microorganisms feed on the organic matter, they transform it into simpler compounds, releasing nutrients back into the soil, which can then be utilized by plants. In this phase, while there may be some impact on nitrogen availability and soil texture, the main focus is on the activity of microorganisms that lead to the breakdown of organic matter. This decomposition process is vital for maintaining soil health, fertility, and the overall functioning of the ecosystem. By effectively breaking down organic substrates, microorganisms help to stabilize soil aggregates, enhance nutrient cycling, and contribute to the soil's biological activity, ultimately supporting plant growth.
