Plants cannot make protein from pure carbohydrate, because proteins contain nitrogen and sometimes sulphur. They get the nitrogen which they need from the nitrates in the soil.the bacteria called `Rhizobium `lives in the roots of legminous plants and leg. plants need nitrogen to grow pulses.The bacteria called `rhizobium` changes the atmospheric nitrogen in solution form and in return the plants give the bacteria shelter and food thus this is called a symbiotic relationship .

Do most organisms use nitrogen in the form of nitrogen gas?
No. They can not use nitrogen gas because the triple bonds of nitrogen can only be broken down for use in living things, plants, by the symbiotic bacteria in the root nodes. Then in other forms nitrogen is taken up into the plant and from there to other trophic levels.
What form must nitrogen take before plants and animals can use it?
through roots from the soil
What process involves the capture and conversion of nitrogen into a form usable by plants?
Nitrifying bacteria can convert atmospheric nitrogen in to nitrates that plants can use in the soil. That is why leguminous plants having these micro-organisms in the nodules enrich the soil for nitrogen deficiency.
Can nitrogen be fixed naturally for plant use?
Yes. Nitrogen is converted to ammonia by organisms called diozotrophs, which the plants can use It also occurs naturally as a result of lightning strikes and combustion.
Plant and animals can not use the nitrogen that makes up?
The atmospheric nitrogen. This is a diatomic and triple bonded form of nitrogen that can not be metabolized by organisms other than some bacteria which convert it into usable form for plants.
What elements are most organisms unable to take from the atmosphere?
nitrogen
Do most organisms use nitrogen directly form air?
Since the air around you is about 78% nitrogen gas, you might think it would be easy for organisms to retrieve nitrogen easily. However, most organisms cannot use nitrogen gas. Nitrogen gas is called "free" nitrogen because it's not combined with other atoms. Most organisms can use nitrogen only when it has been combined with other elements to form nitrogen-containing compounds. So, is that the answer you were looking for (possibly for homework)?

No. They can not use nitrogen gas because the triple bonds of nitrogen can only be broken down for use in living things, plants, by the symbiotic bacteria in the root nodes. Then in other forms nitrogen is taken up into the plant and from there to other trophic levels.
Can most organisms can use free nitrogen air?
YES!
Plants use nitrogen to make?
Many compounds in plants include Nitrogen including Proteins and DNA. Note, most plants can not use atmospheric Nitrogen (N2), and must absorb nitrogen that is bonded to hydrogen or carbon such as Ammonia (NH3).
Will additional fertilizers, such as nitrogen supplements damage most plants?
The use of nitrogen and other fertilizers will enhance the growth of most plants when used correctly.
What form must nitrogen take before plants and animals can use it?
through roots from the soil
Why is nitrogen fixation necessary?
Most plants use single nitrogen atoms, not N2 molecules.
What process involves the capture and conversion of nitrogen into a form usable by plants?
Nitrifying bacteria can convert atmospheric nitrogen in to nitrates that plants can use in the soil. That is why leguminous plants having these micro-organisms in the nodules enrich the soil for nitrogen deficiency.
What is industrial fixation?
Industrial fixation is a synthetic method of converting atmospheric nitrogen to nitrogen oxides or ammonium ions that plants and other organisms are able to use
Why do organisms need nitrate?
Nitrates and Nitrites are used by some bacteria for energy and plants use them for protien synthesis. (for most other organisms these chemicals tend to be detrimental) Most animals do not use or need nitrate, they need nitrogen which is supplied by ingestion of plant products or animals.
Can nitrogen be fixed naturally for plant use?
Yes. Nitrogen is converted to ammonia by organisms called diozotrophs, which the plants can use It also occurs naturally as a result of lightning strikes and combustion.
