Solution

The correct option is C Nitrogen fixation : Q
Denitrification : P
The assimilation of atmospheric nitrogen by soil bacteria in organic form and then absorbed by plants is called as nitrogen fixation. An organic process during which nitrogen from the soil is removed by denitrifying bacteria is denitrification. Thus, the correct answer is option C.
