Explain all the bio geo chemical cycle.. ( each cycle individually).
PLS HELP FRNDS!!
FAST........

To bolo
Neeche wale comment box pe type karte hai
Kyunki mai likh rahi ho ye ans
say asasas11 to write a answer
But she doesnt know
I think.. Wait i will sm of my frnds to see if they know the answer

There are mostly 4 biogeochemical cycles found in nature:-
1) Water Cycle
(I) Evaporation- the water gets converted to gaseous state( water vapour) at a temperature enough to provide particles kinetic energy enough to overcome liquid force of attraction. Due to this, they get converted into vapours and go high in sky.
(II) Condensation- dust, dirt etc. works as nuclei for vapour to get organised. they become organised under that formation and we see them as cloud.
(III) Precipitation- When by natural or artificial factor, pressure of clouds rises or temperature decreases, they precipitate i.e. drops out the water. i.e. vapours changes to water . In cold areas, precipitation is in the form of hail, snow etc.
2) Nitrogen. Cycle
(I) Atmospheric nitrogen is found to constitute 78% of air.
(II) Need for nitrification- plants which synthesis protein requires Nitrogen. they can't use atmospheric nitrogen . So, there is a need for nitrification.
(III) Nitrication- Certain bacterias( Rhizobium etc.) & blue green algae ( nostoc, anabaena, cyanobacteria etc.) convert atmospheric nitrogen into suitable compound to be used by plants.
(IV) Ammonification- when the plants, which utilises these compounds of nitrogen dies, or the animals which eat these compound die, they get converted into nitrogen compounds, this process is known as ammonification.
(V) Denitrification- Certain bacterias convert compounds of nitrogen into atmospheric nitrogen.
3) Carbon Cycle
(I) Respiration- During respiration oxygen gets converted into carbon dioxide ( a compound of carbon ) .
(II) Photosynthesis- Carbon Dioxide gets used up and oxygen gets released as a byproduct.
(III) Formation of fossil carbon fuels- When plants and animals die, their remains under high pressure and high temperature, gets converted into fossil carbon fuels.
(IV) Combustion of carbon fuels- When carbon fuels get combusted,they release carbon dioxide.
4) Oxygen Cycle
(I) Respiration- oxygen gets used up and carbon dioxide is released.
(II) Photosynthesis- carbon dioxide gets used up and oxygen gets released.
