Bacteria Certain bacteria can use nitrogen from the air to make nitrogen-containing substances called nitrites. Other bacteria can turn nitrites into nitrates-another group of nitrogen-containing substances.
Nitrogen fixing is a process whereby certain bacteria convert basic nitrogen to nitrogen compounds that can be absorbed by a plant's root system, for use by the plant. You can compare this to human metabolism; the human body needs iron, but we cannot eat nails or iron bars to accomplish this. We must first convert the iron to compounds that our body can assimilate, digest and absorb.
Nitrogen compounds have more than one source in nature. Nitrogen fixing bacteria, found in the root nodules of leguminous plants, are a major source. Lightning produces a certain amount of nitric oxide (through combustion of oxygen and nitrogen in the atmosphere) which dissolves in the rain to form nitric acid, which also contributes biologically usable nitrogen.
Proteins are organic compounds, mostly composed of hydrogen, oxygen, nitrogen and carbon with some trace elements. The first three are obtained from water and the air, while the nitrogen and trace elements are acquired primarily via the roots from minerals (or fertilizer) in the soil.
OK well free nitrogen is fixed by bacteria that live in the soil. some bacteria live in nodules, or bumps , on certain plant roots. the bacteria get food from the plants, and plants absorb fixed nitrogen from the bacteria. animals get nitrogen by eating plants or by eating prey that have eaten plants. fixed nitrogen may enter the soil in other ways too. a small amount of free nitrogen in the air by lighting. it is carried to the ground by rainfall. fixed nitrogen also enters the soil because of decomposers. decomposers break down dead organisms, and fixed nitrogen is released in the soil. the fixed nitrogen can be absorbed by plant roots.

From lightening and nitrogen-fixing bacteria in the roots of certain plants.
ok so............... nitrogen fixation helps the plants and the bacteria to convert atmospheric nitrogen into the amonia ....amonium...nitrate and nitrite {simple substances of nitrogen}............these are the only forms of nitrogen that could be used by the plants

Living things that need nitrogen to make complex nitrogen compounds are called nitrogen-fixing organisms. These organisms have the ability to convert atmospheric nitrogen gas (N2) into usable forms such as ammonia or nitrates, which can be incorporated into various biological molecules. Examples of nitrogen-fixing organisms include certain bacteria and some plants, such as legumes.

Bacteria =========================== Specifically a particular type of bacteria that live in nodules on the roots of certain plants (eg the Legume family) called "Nitrogen Fixing Bacteria" . Not other bacteria decompose organic material and release nitrogen back into the atmosphere.
In soil. Especially around certain plants (legumes).
it is The ability to fix nitrogen is found only in certain bacteria and archaea.
Certain plants are nitrogen fixers. Alfalfa is one.
Stomach bacteria is naturally neutralized with acidic or certain compounds in foods. If you drink lemon juice or orange juice, the bacteria will be suppressed. Also, compounds found in chili peppers are known to kill any bad bacteria.
