Answer 1

The correct option is B $\begin{array}{cccc}\text{A}& \text{B}& \text{C}& \text{D}\\ \text{Denitrification}& \text{Ammonification}& \text{Plants}& \text{Animals}\end{array}$

Nitrogen cycle is a biogeochemical process through which nitrogen is converted into many forms, consecutively passing from the atmosphere to the soil to organism and back into the atmosphere. It involves several processes such as nitrogen fixation, nitrification, denitrification, decay and putrefaction.



A - Denitrification, B - Ammonification, C - Plants, D - Animals
