Question
Select the correct statement.
- Most important nutrient for plants is nitrogen.
- Major reservoir for plants is atmosphere.
- Nitrogen cycle is a sedimentary cycle.
- All of the above
Hint:
By far the largest reservoir of total nitrogen on Earth is the dinitrogen gas (N2) in the atmosphere.
The correct answer is: Major reservoir for plants is atmosphere.
The atmosphere is the major reservoir for plants - Without the help of the atmosphere, plants would not have survived, and plants have to depend on the atmosphere for essential inorganic components like carbon dioxide, phosphate, etc.
