Question

How do plants absorb Nitrogen? answer for class 7​

Answer 1

Answer:

This is your answer- Nitrogen assimilation in plants. Plants absorb nitrogen from the soil in the form of nitrate (NO3−) and ammonium (NH4+). In aerobic soils where nitrification can occur, nitrate is usually the predominant form of available nitrogen that is absorbed. ... Ammonium ions are absorbed by the plant via ammonia transporters.

Explanation:

Plants cannot themselves obtain their nitrogen from the air but rely mainly on the supply of combined nitrogen in the form of ammonia, or nitrates, resulting from nitrogen fixation by free-living bacteria in the soil or bacteria living symbiotically in nodules on the roots of legumes

Answer 2

Answer:

There are certain bacteria called Rhizobium which can turn atmospheric nitrogen into a soluble form. These bacteria are found in leguminous plants...Other plants are replenished with nitrogen when farmers add fertilizers containing plant foods like nitrogen, phosphorus and potassium
