Answer 2

$\huge { \mathtt {\underline{ \underline{nitrogen \: \: \: cycle}}}}$

⬇⬇

$\large {\boxed {\mathtt{ atmospheric \: \: \: nitrogen }}}$

$\large \implies \: { \boxed{ \mathtt {lightning}}}$

$\large \implies \:{ \boxed {\mathtt{compounds \: of \: nitrogen \: in \: the\: soil}}}$

$\large \implies { \boxed {\mathtt{bacteria \: turn \: compounds \: of\:nitrogen \: into \: gaseous \: nitrogen}}}$

.

our atmosphere has 78% Nitrogen gas.

NITROGEN is one of the essential constituent of all living organisms as part of proteins, chlorophyll, nucleic acid and vitamins.

The atmospheric nitrogen cannot be taken directly by plants and animals.

• Certain bacteria and blue green algae present in the soil fix nitrogen from the atmosphere and convert it into compounds of Nitrogen.

• Once nitrogen is converted into this usable compounds, it can be utilised by plants from the soil through their root system.

NITROGEN is then used for the synthesis of plant proteins and other compounds.

Animals feeding on plants get these proteins and other nitrogen compounds.
