Question

In the nitrogen cycle, which of the following play an important role? 

पर्याय

• Rhizopus

• Nitrobacter

• Mucor

• Chlamydomonas 

Answer 1

Nitrobacter

Explanation:

A microbe called Nitrobacter fixes air-free nitrogen into soluble salts like nitrites and nitrates. Plants take up the fixed N₂, which is subsequently transferred down the food chain to herbivores and predators. As a result, it is crucial for the N₂ cycle.
