ANSWER:
Plants absorb nitrogen from the soil.
EXPLANATION:
- Nitrogen is absorbed by the roots of the plants in the form of amino acids, nitrate or nitrite ions.
- The nitrogen absorbed from the soil by roots is then transported to the various parts of the plants. Plants do not get nitrogen they need directly from the air.
- This is because the organic nitrogen that is available in the atmosphere is not usable for plants. Plants need non-organic nitrogen which is obtained by changing organic nitrogen into non-organic forms by the bacteria in the soil.
