define nitrogen fixation

Answer 1

Answer:

the chemical processes by which atmospheric nitrogen is assimilated into organic compounds, especially by certain microorganisms as part of the nitrogen cycle.

Answer 2

The nitrogen molecule in the atmosphere is a non-reactive di-Nitrogen molecule. As a result, plants and other living organisms are unable to use it.

Explanation:

• It is necessary to convert non-usable nitrogen into usable nitrogen. Nitrogen fixation is the name given to this process. This process converts molecular nitrogen into useful forms or compounds, such as ammonia or other nitrogenous components, which are then combined in the soil.
• To explain nitrogen fixation, it is one of the first steps in the nitrogen cycle, and it occurs through the use of bacteria such as azotobacter, rhizobium, and others, as well as natural processes.
• When molecular nitrogen is transformed to ammonia in the presence of a biological catalyst known as nitrogenize, this is an example of a biological nitrogen fixation mechanism (BNF). This chemical is found in microbes such as frankia, symbiotic rhizobium, azotobacter, and others as a naturally occurring catalyst.
