Question

The atmosphere acts as a reservoir

A Water cycle
B Carbon cycle
C Nitrogen cycle
D Phosphorus cycle
E None of them

F All cycles are correct.

Answer 1

Answer. Option F

Atmosphere is a blanket of gases that surrounds the earth. During the water cycle, there is a step in which water evaporation takes from the water bodies and leads to the formation of clouds. These clouds are also suspended in the atmosphere and when precipitation occurs water reaches the earth's surface and the cycle proceeds further.

In the carbon cycle, carbon dioxide is present in the atmosphere due to the exhalation of human beings, burning of fossil fuels etc. This carbon dioxide is then used by the plants for photosynthesis and the cycle proceeds with further steps.

In nitrogen cycle, nitrogen combines with oxygen to form the nitric oxide during the atmospheric nitrogen fixation and the energy is provided by the thundering. Beside this, biological nitrogen fixation also releases various forms of nitrogen into the atmosphere.

In the phosphorus cycle, the phosphorus present in the atmosphere through the weathering process of the rocks reaches the earth's surface by precipitation and then various steps are carried out to complete the cycle.

Thus, from the above text it is clear that atmosphere is participating regularly in each cycle. Thus, the chosen option is justified.
