Question

how do plants get nitrogen from the air??

Answer 1

Hlo dued...

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

Explanation:

$\huge{ \mid{ \pink{ \underline{ \overline{ \orange{answer....}}}}}}$

Plants do not get their nitrogen directly from the air. Although nitrogen is the most abundant element in the air, every nitrogen atom in the air is triple-bonded to another nitrogen atom to form molecular nitrogen, N2.

Plants get the nitrogen that they need from the soil, where it has already been fixed by bacteria and archaea. Bacteria and archaea in the soil and in the roots of some plants have the ability to convert molecular nitrogen from the air (N2) to ammonia (NH3), thereby breaking the tough triple bond of molecular nitrogen. Such organisms are called "diazotrophs". From here, various microorganisms convert ammonia to other nitrogen compounds that are easier for plants to use. In this way, plants get their nitrogen indirectly from the air via microorganisms in the soil and in certain plant roots. Note that lightning and high-energy solar radiation can also split the nitrogen molecule, and therefore also fixes the nitrogen in the air. However, the amount of nitrogen fixed by lightning and solar radiation is insignificant compared to the amount fixed by diazotrophs in the soil and in roots.
