Choose the incorrect statement
Higher plants generally utilize the reduced forms of nitrogen such as nitrate ( ) and nitrite (
)
Nitrogen exists as two nitrogen atoms joined by a very strong triple covalent bond (N ≡N).
Decomposition of organic nitrogen of dead plants and animals into ammonia is called ammonification.
The nitrates are soluble in water and are directly absorbed by the roots of the plants.
Higher plants generally utilize the oxidized forms such as nitrate and nitrite
or the reduced form (N) of nitrogen which is made available by a variety of nitrogen fixers. Hence, the correct answer is option a.
