During non-biolocigal `N_(2)` fixation the nitrogen is converted into nitrogen oxides by the help of:

Options

A. Rhizobium
B. Lightining
C. UV-radiation
D. More than one options are correct

Answer

**Step-by-Step Solution:**

1. **Understanding Nitrogen Fixation:**
- Nitrogen fixation is the process of converting atmospheric nitrogen (N₂) into a usable form, primarily ammonia (NH₃). This process is essential for making nitrogen available to living organisms.

2. **Types of Nitrogen Fixation:**
- There are two main types of nitrogen fixation:
- **Biological Nitrogen Fixation:** This is carried out by certain prokaryotic organisms, such as bacteria (e.g., Rhizobium).
- **Non-biological Nitrogen Fixation:** This occurs without the involvement of living organisms.

3. **Non-biological Nitrogen Fixation Mechanisms:**
- Non-biological nitrogen fixation can occur through natural phenomena such as:
- **Lightning:** The high energy from lightning can break the nitrogen molecules and allow them to react with oxygen in the atmosphere, forming nitrogen oxides (NO and NO₂).
- **Ultraviolet (UV) Radiation:** UV radiation can also provide enough energy to facilitate the conversion of nitrogen gas into nitrogen oxides.

4. **Conclusion:**
- The question asks about non-biological nitrogen fixation and how nitrogen is converted into nitrogen oxides. The correct answer is that nitrogen is converted into nitrogen oxides by the help of lightning and UV radiation. Therefore, more than one option is correct.

**Final Answer:**
During non-biological nitrogen fixation, nitrogen is converted into nitrogen oxides with the help of lightning and UV radiation.
