Question

Can anyone please define nitrogen fixation process completely? ​

Answer 1

Answer:

HI MATE !

NITROGEN FIXATION :- ⬇️

• Nitrogen fixation, any natural or industrial process that causes free nitrogen (N2), which is a relatively inert gas plentiful in air, to combine chemically with other elements to form more-reactive nitrogen compounds such as ammonia, nitrates, or nitrites.

• Under ordinary conditions, nitrogen does not react with other elements. Yet nitrogenous compounds are found in all fertile soils, in all living things, in many foodstuffs, in coal, and in such naturally occurring chemicals as sodium nitrate (saltpetre) and ammonia. Nitrogen is also found in the nucleus of every living cell as one of the chemical components of DNA.

Answer 2

♧ANSWER♧

Nitrogen fixation is the essential biological process and the initial stage of the nitrogen cycle. In this process, nitrogen in the atmosphere is converted into ammonia (another form of nitrogen) by certain bacterial species like Rhizobium, Azotobacter, etc. and by other natural phenomena.

• Plants are the main sources of food.
• The nutrients obtained from plants are synthesized by plants using various elements which they obtain from the atmosphere as well as from the soil.
• This group of elements includes nitrogen as well. Plants obtain nitrogen from the soil and utilise in the process of protein synthesis.
• Unlike carbon dioxide and oxygen, atmospheric nitrogen cannot be obtained through stomata of leaves.
• Because the nitrogen gas present in the atmosphere can not be directly used by plants.
• There are certain bacteria and some natural phenomenon which help in Nitrogen fixation.

EXAMPLE

Nitrogen fixation by bacteria is an example of the symbiotic relationship between Rhizobium and the leguminous plants. While bacteria fix nitrogen in the soil, plants provide them food.

NITROGEN FIXATION BY LIGHTNING

Another process which helps in nitrogen fixation is lightning. It is a natural phenomenon where the energy of lightning breaks and converts the non-absorbable form of nitrogen into a usable form. Even though the contribution of lightning in the nitrogen fixation is small, they save plants from the deficiency of essential elements.
