Answer:Human activity affects cycling of nitrogen.
In general, human activity releases nitrogen into the environment by two main means: combustion of fossil fuels and use of nitrogen-containing fertilizers in agriculture. Both processes increase levels of nitrogen-containing compounds in the atmosphere.
Explanation:
The human activities can change the levels of nitrogen into the atmosphere and thus impacting other cycles on Earth.
A biogeochemical cycle by which nitrogen is transformed into various chemical forms as it circulates between the terrestrial, atmosphere, and marine ecosystems.
The transformation of nitrogen can take place by both physical and biochemical procedures.
Generally, the activity of humans discharges nitrogen into the surrounding mainly by two means, that is, use of nitrogen containing fertilizers in agriculture and combustion of fossil fuels.
Both the methods enhance the levels of nitrogen-containing components into the atmosphere.
With enhanced availability of nitrogen there seems a change in carbon storage, thus, influencing more procedures than just the nitrogen cycle.
Thus, human activities like use of fertilizers and burning of fossil fuels, the concentration of nitrogen increases in the atmosphere.
