Nitrogen
• Nitrogen is the 7th element on the periodic table.
• Nitrogen is a very important element since it is essential in
the production of amino acids, nucleic acids and proteins.

to be FIXED into ammonia or nitrates before starting to
move through the ecosystem.

The name of the bacteria which live on the
root nodules of legume plants and carry
out nitrogen fixation is
There are some other methods for the
production of nitrogen compounds but the one
which accounts the most is
Emission from combustion engines
Nitrogen burning in lightning
NITROGEN FIXATION
Manufacture of fertilizers
