Humification results in the formation of _______substance.

Options

A. Colloidal , Basic
B. Acidic ,light coloured
C. Amorphous,dark coloured
D. Light coloured, Colloidal

Answer

**Step-by-Step Solution:**

1. **Understanding Humification**: Humification is the process through which organic matter, such as dead leaves and other plant materials, is broken down by decomposers like earthworms and microorganisms. This process is essential for nutrient cycling in ecosystems.

2. **Fragmentation**: Initially, the dead organic matter undergoes fragmentation. This is where larger pieces of organic material are broken down into smaller fragments by the action of decomposers.

3. **Decomposition**: Following fragmentation, the smaller fragments go through decomposition, where they are further broken down into simpler substances. This process is known as catabolism.

4. **Formation of Humus**: As decomposition progresses, a dark-colored, amorphous, and colloidal substance begins to form. This substance is known as humus. Humus is significant because it is highly resistant to further decomposition and serves as a reservoir for essential minerals.

5. **Characteristics of Humus**: Humus is characterized by its dark color, amorphous nature, and colloidal properties. It decomposes very slowly and eventually contributes to the mineralization process, where nutrients are released back into the soil.

6. **Final Answer**: Therefore, humification results in the formation of **humus**.
