During biology nitrogen fixation, nitrogen is converted to

Options

A. ammonia
B. nitrate
C. nitrite
D. amino acid

Answer

**Step-by-Step Solution:**

1. **Understanding Nitrogen Fixation**: Nitrogen fixation is the process by which atmospheric nitrogen (N₂) is converted into a more usable form for living organisms, primarily plants. This process can occur through biological means, which involves living organisms, or through non-biological means such as lightning or industrial processes.

2. **Biological Nitrogen Fixation**: In biological nitrogen fixation, certain prokaryotic organisms (bacteria) play a crucial role. These organisms are capable of converting atmospheric nitrogen into ammonia (NH₃), which is a form that plants can readily utilize.

3. **Role of Prokaryotes**: Prokaryotic species, such as Azotobacter, Anabaena, Nostoc, and Rhizobium, possess an enzyme called nitrogenase. This enzyme facilitates the reduction of atmospheric nitrogen to ammonia.

4. **Conversion Process**: The primary product of biological nitrogen fixation is ammonia. This ammonia can then be further converted into other nitrogenous compounds such as nitrate (NO₃⁻), nitrite (NO₂⁻), and amino acids, which are essential for plant growth and development.

5. **Conclusion**: Therefore, during biological nitrogen fixation, nitrogen is primarily converted to ammonia.

**Final Answer**: During biological nitrogen fixation, nitrogen is converted to ammonia.
