Consider the following statements:

1. The two major natural pathways of nitrogen fixation are lightning and biological activity.

2. Fixation of nitrogen cannot be done through the use of chemical fertilizers.

Which of the statements given above is/are correct?

The transfer of atmospheric nitrogen into soils or nitrogen fixation means the conversion of atmospheric molecular nitrogen into usable forms in the soils which can be taken by the plants through their roots, the process known as root osmosis. There are only two major natural pathways of nitrogen fixation or conversion of molecular atmospheric nitrogen into ammonia, nitrate ion or amino acids example (i) lightning and (ii) biological activity.

There is also artificial fixation of nitrogen by men through the use of chemical fertilizers.
