Answer Details
Decomposition of soil organic matter is mainly caused by bacteria. Bacteria are single-celled microorganisms that are ubiquitous in soil and are responsible for breaking down complex organic matter into simpler forms. They play a vital role in the cycling of nutrients in soil ecosystems. When organic matter is added to soil, bacteria break down the complex molecules into smaller molecules such as sugars, amino acids, and fatty acids, which can then be used by plants for growth and development. Bacteria also help to release nutrients from organic matter into the soil, making them available for plant uptake. Without bacteria, organic matter would accumulate in the soil and become unavailable for plant growth.
