Select the correct statement.

  1. Most important nutrient for plants is nitrogen. 
  2. Major reservoir for plants is atmosphere.
  3. Nitrogen cycle is a sedimentary cycle.
  4. All of the above

hintHint:

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.
