The correct Answer is:
To answer the question "What is required for nitrogen fixation by Rhizobium?", we can break down the solution into several steps: ### Step-by-Step Solution: 1. **Understand Nitrogen Fixation**: Nitrogen fixation is the process by which atmospheric nitrogen (N₂) is converted into ammonia (NH₃), a form that plants can use. 2. **Identify the Role of Rhizobium**: Rhizobium is a type of nitrogen-fixing bacteria that forms a symbiotic relationship with leguminous plants (like peas and beans). They reside in the root nodules of these plants. 3. **Determine Nutrient Requirements**: For Rhizobium to effectively fix nitrogen, certain nutrients are necessary. Among the options provided (potassium, phosphorus, nitrate, and sodium), we need to identify which one is essential. 4. **Focus on Phosphorus**: Phosphorus is crucial for the growth and functioning of Rhizobium. It plays a significant role in energy transfer and is vital for the synthesis of nucleic acids and ATP, which are important for the nitrogen fixation process. 5. **Conclusion**: Therefore, phosphorus is required for nitrogen fixation by Rhizobium, enhancing the symbiotic relationship with legume crops and facilitating the conversion of atmospheric nitrogen into a usable form for plants. ### Final Answer: Phosphorus is required for nitrogen fixation by Rhizobium. ---
