Standing state of the ecosystem is:

Options

A. Living and non-living components
B. Only living components
C. Total weight of inorganic nutrient
D. None of the above

Answer

**Step-by-Step Solution:**

1. **Understanding the Concept of Standing State:**
- The standing state of an ecosystem refers to the total amount of nutrients present in that ecosystem. It is a measure of the nutrient content, which includes both living and non-living components.

2. **Analyzing the Options:**
- **Option 1: Living and non-living organic components.**
- This option suggests that the standing state includes both living and non-living components. However, the standing state primarily focuses on the nutrient content, which is more related to non-living components. Therefore, this option is not correct.

- **Option 2: Only living components.**
- This option indicates that the standing state consists solely of living components. However, the standing state does not account for living organisms; it is more about the nutrients available in the ecosystem. Thus, this option is also incorrect.

- **Option 3: Total weight of inorganic nutrients.**
- This option states that the standing state refers to the total weight of inorganic nutrients. This aligns with the definition of standing state, as it focuses on the nutrient content, which is primarily inorganic. Therefore, this is the correct option.

- **Option 4: None of the above.**
- Since we have identified Option 3 as the correct answer, this option cannot be correct.

3. **Conclusion:**
- After evaluating all the options, the correct answer to the question "Standing state of the ecosystem is:" is **Option 3: Total weight of inorganic nutrients.**
