Question
The micro-organisms that convert the dead plants and animals to humus are known as:
The correct answer is
Decomposers
Decomposers: Converting Organic Matter to Humus
The process of decomposition is vital for nutrient cycling in ecosystems. Specific micro-organisms are responsible for breaking down dead organic material.
- Decomposition: This is the process where complex organic matter from dead plants and animals is broken down into simpler inorganic substances.
- Humus Formation: A key outcome of decomposition is the formation of humus, which is the stable, dark, nutrient-rich organic material found in soil.
- Role of Micro-organisms: Certain micro-organisms, primarily bacteria and fungi, act as decomposers. They consume the dead organic matter and facilitate its breakdown.
- Conclusion: Therefore, the micro-organisms that convert dead plants and animals into humus are called decomposers.
The correct option is 4, Decomposers.
