The key reason is to help them make proteins
Amino acids make up proteins, and one of the things which makes up amino acids is nitrogen
Proteins are used for the growth of the plant, and also the repair and replacement of parts of the plant when it is damaged
What does it mean to say the "need of nitrogen in the atmosphere"? Needed for who, for what? Nitrogen is in the atmosphere regardless of who needs it.Is the nitrogen gas used for something? Definitely. Certain organisms are able to convert nitrogen gas, N2, in the atmosphere into NH3, ammonia, which is used as a plant nutrient. This is generally called nitrogen fixation.
The reason nitrogen is abundant in the atmosphere yet limits plant growth is that plants cannot make use of elemental nitrogen. The bond between the nitrogen atoms in elemental nitrogen (which is a diatomic gas) is very strong and not easily broken. Therefore, plants must rely on bacteria in order to fix the nitrogen (convert it into a usable form).
they get threw their roots and it is called nitrogen fixation
Nitrogen is more in the atmosphere. Around 78% of the atmosphere is nitrogen gas and 21% is oxygen gas.
Nitrogen is found in the atmosphere as diatomic elemental nitrogen, N2.
The nitrogen goes into the nodules of the plant.

Transpiration
The nitrogen goes into the soil and then into the atmosphere through denitrification ;)
Urea is the plant fertilizer that is highest in nitrogen. The nitrogen-rich chemical compound may be found in mammal urine and represents the highest nitrogen content of all high-nitrogen plant fertilizers. It offers the disadvantage of converting to vaporized forms that occupy the atmosphere, not the soil and its soil food web members such as plant roots.

because most of our atmosphere has nitrogen in it
Nitrogen fixing bacteria are anaerobic bacteria present in the soil or in some plant roots that change nitrogen gas from the atmosphere into solid nitrogen compounds (e.g. ammonium salts) that plants can use in the soil.Nitrogen fixing bacteria that are symbiotic with plants use sugars supplied by the plant they live in to provide the metabolic energy to carry out this process.
yes because if it is gathered, we will sstill have the same atmosphere
