Which of the following statements is not true about nitrogen fixation?

1)

it is the conversion of nitrate or ammonia to atmospheric nitrogen
2)

bacteria can biologically fix nitrogen
3)

ammonia can be converted to salts to use as fertilizers
4)

inorganic fertilizers are produced using industrial nitrogen fixation
5)

lightning and sunlight can convert n2 to no3 in the atmosphere

1)   It is the conversion of nitrate or ammonia to atmospheric nitrogen

Explanation:

Nitrogen fixation -

It is the process in which the nitrogen in the molecular from is converted to ammonia .

It is one of the essential process , and is done by the help of rhizobium bacteria which are present in the roots of some specific plants .

The ammonia formed can be easily converted to fertilizers .

Hence , the incorrect statement about nitrogen fixation is 1)   It is the conversion of nitrate or ammonia to atmospheric nitrogen .

true. earthquakes are felt whenever there is a slip around a fault in the rocks below the earth. this reorientation of faults create sesmic waves and is known as earthquake, the severity of which is measured in richter scale. these are more prominent in hilly regions as the rocks usually form faults to balance the pressures on it.
