How nitrogen Absorb by the plant? and how proteins consumed by the human beings from plant ?
Answers
Explanation:
Plants take nitrogen from the soil by absorption through their roots as amino acids, nitrate ions, nitrite ions, or ammonium ions. Plants do not get their nitrogen directly from the air. Plants get the nitrogen that they need from the soil, where it has already been fixed by bacteria and archaea.

Answer:
Plants absorb nitrogen from the soil in the form of nitrate (NO3−) and ammonium (NH4+). In aerobic soils where nitrification can occur, nitrate is usually the predominant form of available nitrogen that is absorbed.[1][2] However this is not always the case as ammonia can predominate in grasslands[3] and in flooded, anaerobic soils like rice paddies.[4] Plant roots themselves can affect the abundance of various forms of nitrogen by changing the pH and secreting organic compounds or oxygen.[5] This influences microbial activities like the inter-conversion of various nitrogen species, the release of ammonia from organic matter in the soil and the fixation of nitrogen by non-nodule-forming bacteria.
