Question
By which of the following processes can nitrogen fixation take place?
- Floods
- Raining
- Earthquake
- Lightning
Hint:
Nitrogen-fixing is the process by which the nitrogen which is present in the atmosphere can be converted into certain compounds so that it can be used by plants and animals. There are ways by which the nitrogen can be fixed and they are industrial processes, lightning, etc. the nitrogen is to be fixed because animals and plants are not able to use the direct nitrogen present in the atmosphere. Nitrogen is essential for the survival of life because it is used in protein.
The correct answer is: Lightning
By Lightning nitrogen fixation take place.
