Q. 15.0( 3 Votes )

Match the contents of the column I and column II.

Answer :

a) Carbon dioxide iii) GHG (greenhouse gas)


Carbon dioxide is a gas molecule with three atoms. They capture outgoing infrared energy from the earth, thereby warming the planet.


b) Nitrogen fixation i) Bacteria


Soil bacteria perform nitrogen fixation by converting atmospheric nitrogen N2 into ammonia NH3. This ammonia is used by plants to synthesize proteins.


c) CFCs (chlorofluorocarbons) ii) ODS (Ozone depletion substances)


Chlorofluorcarbons are compounds that contain chlorine. One chlorine atom destroys 100,000 ozone molecules when it combines with bromine in the atmosphere. Hence, chloring containing compounds are ozone depleting subtances.


d) Decomposers v) Mineralization


Decomposers (Soil microorganisms) convert organic substances into inorganic substances by mineralization.


e) Oxides of nitrogen and sulphur iv) Fossil fuels


Fossil fuels when burned, release oxides of nitrogen into the atmosphere. Many fossil fuels also contain sulphur impurities, when these are burned the sulphur is oxidised to form sulphur oxide.
