Answer

To answer the question regarding the correct statements about humus, let's break down the information step by step.

### Step-by-Step Solution:

1. **Definition of Humus**:
- Humus is a dark brown organic substance formed from the decomposition of dead leaves and plants. It is a crucial component of soil that enhances its fertility.

2. **Color of Humus**:
- Humus is typically described as dark brown in color, not black. This is an important characteristic to note.

3. **Nature of Humus**:
- Humus is amorphous, meaning it does not have a definite crystalline structure. This distinguishes it from many other organic compounds that may form crystals.

4. **Composition of Humus**:
- Humus is composed entirely of organic matter, derived from the decay of plant and animal material. Therefore, it is incorrect to classify humus as inorganic.

5. **Behavior in Water**:
- Humus does not float on water; instead, it interacts with water to improve soil structure and moisture retention.

6. **Conclusion**:
- Based on the above points, the correct statement about humus is that it is dark brown in color, amorphous, and composed of organic material.

### Final Answer:
The correct statement about humus is that it is dark brown in color, amorphous, and organic in nature.
