Which of the following acts as "nature's scavengers"?

Options

A. Insects
B. Microorganisms
C. Man
D. Animals

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks which of the given options acts as "nature's scavengers."

2. **Identifying the Options**: The options provided are:
- Insects
- Microorganisms
- Man
- Animals

3. **Defining "Nature's Scavengers"**: The term "nature's scavengers" refers to organisms that help in the decomposition of dead organic matter. These organisms play a crucial role in recycling nutrients back into the ecosystem.

4. **Identifying Decomposers**: Decomposers are primarily microorganisms such as bacteria and fungi. They break down dead organic matter into simpler inorganic substances, which can then be utilized by producers (like plants) in the ecosystem.

5. **Analyzing Each Option**:
- **Insects**: While some insects do play a role in decomposition, they are not primarily classified as decomposers.
- **Microorganisms**: This option is correct as microorganisms (like bacteria and fungi) are the main decomposers in nature.
- **Man**: Humans do not act as scavengers in the ecological sense; they are not decomposers.
- **Animals**: Similar to insects, some animals may assist in the breakdown of organic matter, but they are not the primary decomposers.

6. **Conclusion**: Based on the analysis, the correct answer is **Microorganisms** (Option B), as they are the primary decomposers and thus can be referred to as "nature's scavengers."
