Question

Nitrogen fixation is the

conversion of gaseous nitrogen into an organism friendly form (ammonia (NH4 ). preplanned setting of atmospheric levels of nitrogen at 78% stabilizing elemental nitrogen into a gaseous two-atom molecule (N2) the reduction of nitrate (NO3-) to gaseous nitrogen. the repair of D.N.A. by adding nitrogen to the organism's diet

Answer 1

Nitrogen fixation is the conversion of gaseous nitrogen into an organism friendly form (ammonia) .

Step-by-step explanation:

Nitrogen fixation -

It is very important and necessary process by which the nitrogen gas present in the atmosphere gets converted to nitrogen derivatives like ammonia in the soil , is referred to as the process of nitrogen fixation.

This occurs due to the reason , that the derivatives of nitrogen are of much more importance than the molecular nitrogen.

Biologically the process is done by the rhizobium bacteria .

Hence ,

From the question,

The correct option is a.
