Explanation:

Nitrogen adds to the nitrogen cycle on the planet Earth, by Volcanic Action, Excretion of urea by animals, Decay of organic matter and Burning of biomass.

Burning biomass emits large amounts of pollutants, just like burning other solid fuels such as coal. Burning organic material emits particulate matter (PM), nitrogen oxides (NOx), carbon monoxide (CO), sulfur dioxide (SO2), lead, mercury, and other hazardous air pollutants (HAPs).

By the process photosynthesis, Oxygen is added to the atmosphere.
