Question

how does mocro organisms help in nitrogen fixation​

Answer 1

Answer:

Microorganisms such as rhizobium bacteria helps in the nitrogen fixation. It has an symbiotic relationship with with the leguminous plants. This live in the root root nodules of the leguminous plants and fix the nitrogen according to the plants use. Therefore, this proves that the microorganisms help in the nitrogen fixation.

Answer 2

• Nitrogen-fixing bacteria are microorganisms that are capable of converting nitrogen from the environment into fixed nitrogen (inorganic chemicals that plants may use).
• Bacteria in the nodules convert free nitrogen to ammonia, which the host plant utilises for growth.
• Nitrogen fixation is a chemical process that turns molecular nitrogen (N 2) in the air into ammonia (NH 3) or other nitrogenous compounds, mainly in soil or water, but also in industry.
• Because atmospheric nitrogen is molecular dinitrogen, a molecule that is largely nonreactive, all but a few microorganisms are unable to use it.
• During biological nitrogen fixation, also known as diazotrophy, the nitrogenase protein complex converts dinitrogen (N2) gas to ammonia (NH3) (Nif).
