Large scale production of the following is the source is good protein

Options

A. Earthworms
B. Potato
C. Starfish
D. Microbes

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks which of the given options is a source of good protein when produced on a large scale.

2. **Analyzing Each Option**:
- **Earthworms**: While earthworms are beneficial for soil fertility, they are not considered a significant source of protein for human consumption.
- **Potato**: Potatoes are primarily a source of carbohydrates, not protein. Therefore, they do not qualify as a good protein source.
- **Starfish**: Starfish are not commonly recognized as a good source of protein either. They do not contribute significantly to protein needs.
- **Microbes**: Microorganisms such as bacteria, yeast, fungi, and algae can be cultivated to produce protein. Specifically, Single Cell Protein (SCP) derived from these microbes is a well-known source of protein and can be used as a food supplement.

3. **Conclusion**: After analyzing all options, the only viable source of good protein on a large scale is **microbes**.

4. **Final Answer**: The correct answer is **microbes**.
