Match the step in the Global Nitrogen Cycle with the correct description.
Nitrogen Mineralization
Denitrification
Nitrification
Nitrogen fixation
Nitrogen Assimilation
1. The Haber process, Cyanobacteria,
Rhizobia and lightning all
accomplish this step in different
ways.
2. Ammonium is converted to nitrate
by aerobic soil bacteria, so that
nitrogen can become more
accessible to primary producers.
3. Primary producers incorporate
nitrogen in the form of nitrate into
their biomass to fuel consumers,
decomposers, detritivores and
scavengers
4. Decomposition of nitrogen-
containing compounds which
returns nitrogen to the soil or
sediment.
5. An anaerobic process in the
Nitrogen Cycle that results in the
production of a potent greenhouse
gas
