.[D] Option (D) is not true because the bacteria involved in the process are not photoautotrophs, but are chemoatutotrphs. These bacteria oxidise inorganic substances like

NH_{3}

and

NO_{2}

and use the released energy hence are called chemoautotrophs. Simultaneously, they help in the conversion of ammonia

(NH_{3})

to absorbable form

(NO_{3}^{-}

and

NO_{3} -)

of nitrogen.
