Biogeochemical Processes

Front

Biogeochemical Cycling

Back

The movement of nutrients and elements through biological, geological, and chemical processes (e.g., carbon, nitrogen cycles).

Front

Nitrogen Fixation

Back

Conversion of atmospheric nitrogen into forms usable by plants, often facilitated by bacteria.

Front

Ammonification

Back

Decomposition of organic nitrogen into ammonia or ammonium.

Front

Nitrification

Back

Conversion of ammonia into nitrate by nitrifying bacteria.

Front

Denitrification

Back

Conversion of nitrates back into nitrogen gas by bacteria, releasing it into the atmosphere.

Front

Assimilation

Back

The process by which plants and animals incorporate nutrients into their tissues.
