Describe the process of decomposition of detritus under the following heads : Fragmentational leaching, catabolism, humification and mineralization.

Explanation

**Step-by-Step Solution:**

**1. Definition of Decomposition:**
- Decomposition is the process of breaking down dead organic matter (detritus) into simpler inorganic substances. This process is essential for recycling nutrients in ecosystems.

**2. Fragmentation (Fragmentational Leaching):**
- The first step in the decomposition of detritus is fragmentation. This process is primarily carried out by detritivores, which are organisms that feed on dead organic matter.
- As detritivores consume the detritus, they break it down into smaller fragments, making it easier for other decomposers to access and further decompose the material.
