Correct answer is (c) Both the steps occur only in photoautotrophs

Q. Carefully read the following reactions carried out by nitrogen fixing bacteria. Identify the statement about these equations which is not true. 2NH3​+3O2​⟶2NO2−​+2H++2H2​O…(A) 2NO23−​+O2​⟶2NO32−​…(B)

Both the step (A) and (B) can be called nitrification

Step (A) carried out by Nitrosomonas or Nitrococcus

Both the steps occur only in photoautotrophs

Step (B) is carried out by Nitrobacter

Correct answer is (c) Both the steps occur only in photoautotrophs

Q. Carefully read the following reactions carried out by nitrogen fixing bacteria. Identify the statement about these equations which is not true.
$2 N H_{3} + 3 O_{2} ⟶ 2 N O_{2}^{-} + 2 H^{+} + 2 H_{2} O \dots (A)$
$2 N O_{2}^{3 -} + O_{2} ⟶ 2 N O_{3}^{2 -} \dots (B)$
