Question

The figure given below shows a part of nitrogen cycle.

Which of the following represents nitrates?

• A. X
• B. Y
• C. Z
• D. All of these

Answer 1

The correct option is A X

Nitrates are represented by ‘X’ as these are produced by conversion of nitrogen to nitrates by Nitrogen-fixing bacteria, while 'Y' represents denitrification, a microbially facilitated process where nitrate is reduced and ultimately produces molecular nitrogen (N₂). 'Z' represents animals as plants are eaten by animals and they produce animal wastes or faeces.
