How is nitrogen fixation carried out?

Answer 1

Nitrogen fixation is the process by which nitrogen is taken from its relatively inert molecular form (N2) in the atmosphere and converted into nitrogen compounds useful for other chemical processes (such as, notably, ammonia, nitrate and nitrogen dioxide).

Answer 2

Nitrogen fixation is carried out by nitrogen-fixing bacteria that convert atmospheric nitrogen gas (N2) into ammonia (NH3) through an enzyme called nitrogenase. This ammonia is then utilized by plants to make proteins and other essential molecules. Some nitrogen-fixing bacteria live symbiotically in the roots of leguminous plants, forming nodules and fixing nitrogen for mutual benefit.

Answer 3

Nitrogen fixation = fixing of atmosphere N2 to reactive form such as ammonia and nitrate . It can ether bt natural or synthetically.

1. Fixation bt living organism .

Exp . by Rhizobium , live in nodules of legume plant

2. Fixation by atmosphere

Exp , by lightning , huge energy involved cause N2 react with O2 form notrogen oxide and dissolve into soil

3. Fixation by haber process

to produce ammonia .

Answer 4

"Nitrogen fixation is a process by which nitrogen in the Earth's atmosphere is converted into ammonia or other molecules available to living organisms. Atmospheric nitrogen or molecular dinitrogen is relatively inert: it does not easily react with other chemicals to form new compounds. The fixation process frees nitrogen atoms from their triply bonded diatomic form, N≡N, to be used in other ways."

Answer 5

Nitrogen fixation is the process by which nitrogen is taken from its relatively inert molecular form (N2) in the atmosphere and converted into nitrogen compounds (such as ammonia,nitrate and nitrogen dioxide). This is an essential process for life because fixed nitrogen is needed to make nucleotides which are needed to make DNA and also to make amino acids which in turn are needed to produce proteins. Nitrogen fixation is performed naturally by a number of different prokaryotes, including bacteria, actinobacteria, and certain types of anaerobic bacteria. Microorganisms that fix nitrogen are called diazotrophs. Some higher plants, and some animals (termites), have formed associations (symbiosises) with diazotrophs. Nitrogen fixation also occurs as a result of non-biological processes. These include lighting, industrially through the Haber-Bosch Process, and combustion.[2] Biological nitrogen fixation was discovered by the Dutch microbiologist Martinus Beijerinck.

Answer 6

It occurs mostly through bacteria.

Answer 7

The process of nitrogen-fixation is done by bacteria. Some live in the soil and roots of certain plants.

Answer 8

Nitrogen fixation which is the natural process of breaking down nitrogen from atmosphere to ammonia NH3. It is done either biologically or abiotically. This process is done by bacteria.

Answer 9

Changing it from a gas (N2) into a compound (often with O2

Answer 10

Effect of environmental stresses on nitrogen fixation, and explain prospects of making new symbiosis.
