Which of the following is the correct set of events involved in the process of decompostion?

Options

A. Metabolism, Degradation, Leaching, Mineralisation
B. Degradation, Fragmentation, Humification, Mineralisation, Leaching
C. Fragmentation, leaching , Anabolism, Mineralisation
D. Fragmentation, Leaching, Catabolism, Humification, Mineralisation

Answer

To determine the correct set of events involved in the process of decomposition, we need to understand the stages that occur when organic matter breaks down. Here is a step-by-step breakdown of the decomposition process:

### Step 1: Understanding Decomposition
Decomposition is the process by which dead organic matter is broken down into simpler organic or inorganic compounds. This process is essential for nutrient cycling in ecosystems.

### Step 2: Identifying the Stages of Decomposition
The decomposition process involves several key stages:

1. **Fragmentation**: This is the first step where complex organic substances are broken down into smaller pieces. Organisms like earthworms play a crucial role in this process by physically breaking down the material.

2. **Leaching**: In this stage, water-soluble nutrients from the fragmented material are dissolved and absorbed by the soil. This process helps in enriching the soil with essential nutrients.

3. **Catabolism**: Here, microorganisms such as bacteria and fungi utilize enzymes to further break down the simpler substances. This process converts the organic matter into simpler compounds.

4. **Humification**: This stage involves the formation of humus, a dark-colored organic matter that improves soil structure and fertility. Humification results from the breakdown of organic matter by microbial activity.

5. **Mineralization**: In the final stage, humus is further decomposed, releasing inorganic nutrients back into the soil, which can be utilized by plants. This step is crucial for maintaining soil health and fertility.

### Conclusion
The correct sequence of events in the decomposition process is:
- Fragmentation
- Leaching
- Catabolism
- Humification
- Mineralization

Thus, the correct answer is the option that lists these five stages in order.
