**Step-by-Step Solution:**

1. **Understanding Microbes**: Microbes, or microorganisms, are tiny living organisms that are generally too small to be seen with the naked eye. The prefix "micro" indicates their small size.

2. **Visibility**: Because of their small size, microbes cannot be observed without the aid of special equipment. They are not visible to the naked eye.

3. **Measurement of Size**: The size of small microbes typically ranges from 0.1 micrometers (µm) to a few micrometers. For example, bacteria can be around 0.5 to 5 µm in size.
