Question

How do plants obtain nitrogen?​

Answer 1

Answer:

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 2

Answer:

Leguminous plants follow the process of nitrogen fixation and convert atmospheric nitrogen into usable compounds, and other plants absorb the prepared nitrogen from the soil.
