groundnut is a source of nitrogen.
The most abundant source of calories in the human body is glycogen, which is stored in the liver and muscles, while the least expensive source of calories is body fat, which is used as a reserve energy source.
Your body is not capable of directly using the nitrogen in air. It is ultimately the source of the nitrogen in the proteins and other nitrogen-containing compounds in your body, but the precursors for these are (mostly) made by nitrogen-fixing bacteria in the soil and then incorporated into molecules by plants. (The "mostly" is because some of the nitrogen used by plants comes from nitrates or ammonia applied as fertilizer.)

Eutrophication
The human body is about 3% Nitrogen
The primary source of nitrogenous waste in animals is the breakdown of proteins and amino acids. This breakdown releases nitrogen-containing compounds like ammonia, urea, or uric acid, which must be excreted from the body to maintain proper nitrogen balance.

the nitrogen in its body is released by the action of decomposers
Protein is a macronutrient that we get from food. It is made up of Carbon, Hydrogen, Oxygen, and Nitrogen. Proteins are the body's only source of nitrogen. When we ingest a protein containging food we excrete the nitrogen in our urine; it is called urea.
When nitrogen intake exceeds the body's nitrogen losses, a person is said to be in a state of positive nitrogen balance. This can occur during times of growth, pregnancy, or recovery from illness. It indicates that the body is using nitrogen to build and repair tissues.
