Options:
A) Rhizopus
B) Nitrobacter
C) Mucoraceae
D) All green algae are photosynthetic
Show Answer
Answer:
Correct Answer: B
Solution:
Nitrobacter is a $ NO_3^- $ oxidizing organism, it oxidizes atmospheric free $ NH_3 $ into soluble salts like nitrites and nitrates.
The fixed $ N_2 $ is absorbed by plants through the process of nitrogen fixation, which is then taken up by plants. The $ N_2 $ is transferred to carnivores through the food chain, hence it is important for the nitrogen cycle.
