Answer 1

Here is ur ans....

1)Carbon cycles=biotic process--photosynthesis, respiration,decomposition.

=abiotic process=burning of fossil fuels,forest fires,volcanic activity.

2)Oxygen cycle=biotic ptocess--photosynthesis, respiration,decomposition.

=abiotic process--combustion,corrosion,rusting,formation of ozone

3)Nitrogen cycle=biotic process--biological nitrogen fixation,ammonification,nitrification,denitrification.

=abiotic process=atmospheric nitrogen fixation,industrial nitrogen fixation.

Hope it helps..........
