Denitrification
Definition
Denitrification is a natural process in which certain bacteria convert nitrates (NO3-) into nitrogen gas (N2), releasing it back into the atmosphere. It occurs primarily in oxygen-depleted environments, such as wetlands and soil.
Analogy
Imagine denitrification as a recycling system for nitrogen. Just like how you recycle paper to make new paper, denitrification recycles nitrates by converting them back into nitrogen gas, allowing it to be reused by other organisms.
Related terms
Nitrogen Fixation: The conversion of atmospheric nitrogen gas (N2) into forms usable by plants through biological or industrial processes.
Nitrification: The process by which ammonia (NH3) is converted into nitrites (NO2-) and then further oxidized to nitrates (NO3-), making nitrogen available for plant uptake.
Eutrophication: The excessive enrichment of water bodies with nutrients, often caused by agricultural runoff or sewage discharge, leading to harmful algal blooms and oxygen depletion.
