In a process called denitrification, other bacteria convert ammonia and nitrate into molecular nitrogen and nitrous oxide (N2O).
Where air was insufficient (though still aerobic) decay is retarded but worse, a process called denitrification occurs in which nitrates and ammonia are biologically broken down into gasses and permanently lost.
When suboxic waters (oxygen essentially absent) occur at depths of less than 300 feet, the combination of high respiration rates, and the peculiarities of a process called denitrification can cause N2O production rates to be 10,000 times higher than the average for the open ocean.
Once the materials are exposed to air, they undergo a process called denitrification and gas bubbles explode in the air.
Without nitrogen-fixing soil life to intervene, a putrefaction process called denitrification results in lost soil fertility, as nitrogen is released as nitrous oxide into the atmosphere.
The demand for regulating services provided by wetlands, such as denitrification and protection against floods and storms, will increase, while the provision of these services is likely to decrease.
At the same time, demand for many of these services (such as denitrification and flood and storm protection) will increase.
In addition to methane emissions, the study also investigated other processes such as denitrification, sedimentation, and aquatic productivity.
With a background ranging from biogeochemistry to paleoceanography, Naqvi has carried out extensive research on the biogeochemistry of oxygen-deficient marine environments, especially denitrification and nitrous oxide cycling.
From an ecological point of view, the biosphere is the "global ecosystem", comprising the totality of biodiversity on earth and performing all manner of biological functions, including photosynthesis, respiration, decomposition, nitrogen fixation and denitrification.
