Question

Plants absorb nitrogen from: the atmosphere the soil water

Answer 1

Plants absorb nitrogen from: the soil ( second choice)

Answer 2

Plants absorb nitrogen from the soil.

Step-by-step 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.
