Question

how do plants absorb nitrogen​

Answer 1

Answer:

By the help of a bacteria called Rhizobium.

Explanation:

Plants don't able to take the nitrogen gas from the air so Rhizobium convert the nitrogen gas into usable form for the plants.

Answer 2

Answer: Plants absorb nitrogen from the soil as both NH₄⁺ and NO₃⁻ ions, but because nitrification is so pervasive in agricultural soils, most of the nitrogen is taken up as nitrate. Nitrate moves freely toward plant roots as they absorb water.
