What is the Nitrogen Cycle?

*The Nitrogen Cycle is the process by which Nitrogen is converted between its various chemical forms.

*The transformation can be carried out through both biological and physical processes.

*Important processes in the Nitrogen Cycle include Fixation,Ammonification,Nitrification, and Denitrification.

*Nitrogen has limited availability for biological use, leading to a scarcity of usable Nitrogen in many ecosystems.
