Question

How nitrogen fixation takes place in the soil ? Explain With the help of a cycle.

Answer 1

Nitrogen fixation takes place with the help of leguminous plants root which absorb nitrogen front air and convert it into nitrates and nitrites molecules which are absorbed by plant

Answer 2

he bacteria live in nodules in the legume roots. Plants cannot absorb nitrogen (N2) from the air. The bacteria convert nitrogen (N2) from the air by adding hydrogen to create ammonium ions (NH4+) which the plants can absorb. Converting thenitrogen by adding hydrogen is what is called “nitrogen fixation” in legumes
