Some food items are stored in refrigerators and deep freezers. Why?

Explanation

### Step-by-Step Text Solution:

1. **Understanding Microbial Growth**: Microorganisms, such as bacteria and fungi, require specific conditions to grow and reproduce. One of the key factors for their growth is temperature.

2. **Role of Refrigerators and Deep Freezers**: Refrigerators and deep freezers are designed to maintain low temperatures. A typical refrigerator operates at around 5 degrees Celsius, while a deep freezer operates at approximately -18 degrees Celsius.

3. **Effect of Low Temperatures on Microbes**: At these low temperatures, the growth and reproduction of microbes are significantly slowed down or halted. This is because the cold environment does not provide the optimum conditions that microbes need to thrive.
