The process of mineralisation by micro organisms helps in the release of

Options

A. inorganic nutrients from humus
B. both organic and inorganic nutrients from detritus
C. organic nutrients from humus
D. inorganic nutrients from detritus and formation of humus

Answer

### Step-by-Step Solution:

1. **Understanding Mineralization**:
- Mineralization is the process through which microorganisms break down organic matter, such as dead plants and animals, converting it into inorganic substances. This process is crucial for nutrient cycling in ecosystems.

2. **Identifying the Role of Microorganisms**:
- Microorganisms, including bacteria and fungi, play a vital role in decomposing organic materials. They help in the breakdown of complex organic compounds into simpler inorganic forms.

3. **Release of Nutrients**:
- During mineralization, the organic matter is decomposed, leading to the release of inorganic nutrients. These nutrients include essential minerals like nitrogen, phosphorus, potassium, calcium, and magnesium, which are vital for plant growth.

4. **Differentiating Between Organic and Inorganic Nutrients**:
- It is important to note that mineralization primarily results in the release of inorganic nutrients. Organic nutrients are not released in this process; instead, they are broken down into simpler forms.

5. **Evaluating the Options**:
- Given the options:
- A) Inorganic nutrients from humus
- B) Both organic and inorganic nutrients from detritus
- C) Organic nutrients from humus
- D) Inorganic nutrients from detritus
- E) Formation of humus
- The correct answer is option A: "Inorganic nutrients from humus," as mineralization specifically refers to the conversion of organic matter into inorganic nutrients.

6. **Conclusion**:
- Therefore, the process of mineralization by microorganisms helps in the release of inorganic nutrients from humus.
