which organism helps in nitrogen fixation
Answer (1)
The organisms that help in nitrogen fixation are mainly certain bacteria. The most well-known are Rhizobium bacteria, which live in the root nodules of leguminous plants like peas, beans, and clover. These bacteria convert nitrogen gas from the air into a form that plants can use, like ammonia. Besides Rhizobium, there are other nitrogen-fixing bacteria such as Frankia, Azotobacter, and cyanobacteria like Anabaena and Nostoc. Some of these bacteria live freely in the soil, while others form a symbiotic relationship with plants. This process is crucial because plants cannot use nitrogen gas directly from the atmosphere and rely on these bacteria to get the nitrogen they need for growth[tex].[/tex]
