NEET BIOLOGY

Detailed explanation-1: -Nitrogen is referred to as a partial mineral element. Its approximate amount in the whole plant is 1-3%. It is present in almost all the living matter; chiefly macro molecules like proteins, nucleic acids and thus, it is an important element in various metabolic processes.

Detailed explanation-2: -Minerals are those elements on the earth and in foods that our bodies need to develop and function normally. Those essential for health include calcium, phosphorus, potassium, sodium, chloride, magnesium, iron, zinc, iodine, chromium, copper, fluoride, molybdenum, manganese, and selenium.

Detailed explanation-3: -However, the four major structural elements in the human body by weight (oxygen, hydrogen, carbon, and nitrogen), are usually not included in lists of major nutrient minerals (nitrogen is considered a “mineral” for plants, as it often is included in fertilizers).

Detailed explanation-4: -Nonmineral elements that are required include oxygen, hydrogen, and carbon. These elements are synthesized by the body. They are only needed in trace amounts.

Detailed explanation-5: -Solution : Nitrogen is not considered a true mineral. It occurs in abundance in the atmosphere. It is inert and plants cannot make use of it directly. It is absorbed by plants in the form of nitrate from the soil, that is why it is sometimes kept under the category of minerals.
