Study the diagram given below and then answer the questions.
State how nitrates in the soil get converted to nitrogen of the atmosphere.

Explanation

**Step-by-Step Solution:**

1. **Understanding Nitrates in Soil**: Nitrates are compounds that contain nitrogen and are commonly found in the soil. They are essential nutrients for plants.

2. **Role of Denitrifying Bacteria**: In the soil, certain types of bacteria, known as denitrifying bacteria, play a crucial role in the nitrogen cycle. These bacteria are responsible for converting nitrates back into nitrogen gas (N₂).

3. **Process of Denitrification**: The process through which denitrifying bacteria convert nitrates to nitrogen gas is called denitrification. During this process, the bacteria use nitrates as a source of energy and, in the process, release nitrogen gas into the atmosphere.
