The correct Answer is:
To solve the question "A0 layer is rich in?", we will analyze the options provided and determine which one correctly describes the composition of the A0 layer of soil. ### Step-by-Step Solution: 1. **Identify the A0 Layer**: - The A0 layer is the topmost layer of the soil, often referred to as the organic layer. It is primarily composed of organic matter. 2. **Examine the Options**: - **Litter**: This refers to the layer of dead plant material, such as leaves and stems, that has not yet decomposed. While it contributes to the organic matter, it is not the primary component of the A0 layer. - **Minerals**: These are inorganic components found deeper in the soil layers (like the A1 or B layers) and are not characteristic of the A0 layer. - **Leachates**: These are solutions that have percolated through the soil, carrying dissolved substances. They are not a primary component of the A0 layer. - **Humus**: This is the dark, organic material in soil that results from the decomposition of plant and animal matter. It is rich in nutrients and contributes significantly to soil fertility. 3. **Determine the Correct Answer**: - Given the definitions and characteristics of each option, the A0 layer is primarily rich in **humus**. This organic matter enhances soil fertility, structure, and moisture retention. 4. **Final Answer**: - The correct answer to the question "A0 layer is rich in?" is **D. Humus**.
