Question

how di plants obtain nitrogen and what is its importance in their growth???​

Answer 1

Answer:

Nitrogen is so vital because it is a major component of chlorophyll, the compound by which plants use sunlight energy to produce sugars from water and carbon dioxide (i.e., photosynthesis). It is also a major component of amino acids, the building blocks of proteins. Without proteins, plants wither and die.

Answer 2

Answer:

Explanation:

Plants obtain nitrogen from the soil by absorbing through their roots as amino acids,nitrate 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.
