The nitrogen cycle is completed with the process of Denitrification
<h3><u>
Explanation:</u></h3>
Denitrification finishes the nitrogen cycle by transforming nitrate behind to vaporous nitrogen. Denitrifying bacteria are the doers of this method. These bacteria utilize nitrate alternately of oxygen while gaining energy, delivering nitrogen gas into the environment.
Denitrification relies on microbial action to crumble freely nitrogen-containing components. Bacilli absorb nitrate to generate energy, but in the method, denitrification transpires and nitrogen is diminished. Denitrification is an anaerobic means, transpiring chiefly in soils and deposits and anoxic zones in ponds and shores.
