Give an example :
A denitrifying bacteria

Explanation

**Step-by-Step Solution:**

1. **Understanding Denitrification**: Denitrification is the process by which nitrates (NO3-) and nitrites (NO2-) in the soil are converted into nitrogen gas (N2), which is released into the atmosphere. This process is crucial for recycling nitrogen in the environment.

2. **Identifying Denitrifying Bacteria**: The organisms that carry out denitrification are known as denitrifying bacteria. These bacteria play a vital role in the nitrogen cycle by helping to maintain the balance of nitrogen in ecosystems.

3. **Examples of Denitrifying Bacteria**: Some well-known examples of denitrifying bacteria include:
- **Pseudomonas species**: A diverse group of bacteria that can thrive in various environments and are known for their ability to denitrify.
