Question

NITROGEN CYCLE
Nitrogen is an important element required by plants for their
growth. Our atmosphere consists of about 78% nitrogen.
Plants either utilise nitrogen present in the atmosphere or from
the fertilisers. Plants cannot use nitrogen from the atmosphere
directly. Therefore, this nitrogen needs to be converted to products
that can be used by the plants. This is called nitrogen fixation.
Plants use this nitrogen and release it back to the atmosphere.
Nitrogen fixation is done by certain bacteria
present in the soil. These bacteria convert
atmospheric nitrogen into usable form such as
soluble nitrates and nitrites. Plants use these
soluble nitrates. The nitrogen is returned to
the atmosphere by different kinds of bacteria.
The process of nitrogen being used by the
plants and animals, and then released back to
the atmosphere is called nitrogen cycle.
NITROGEN FIXATION
Nitrogen cycle involves different steps.
