Question

________ is the biogeochemical cycle that describes the movement of oxygen within and between it's three main reservoirs.

a. Oxygen Cycle
b. Carbon Cycle
c. Nitrogen Cycle
d. Water Cycle

Answer 1

The answer is A........ Oxygen cycle

Answer 2

Oxygen Cycle

Step-by-step explanation:

The bio-geo chemical cycles show the path or movement of any compound like water or element like carbon nitrogen or oxygen. These are the compound or elements essentially present in all living organism and many abiotic factors also.

So we study there transfer from one organism to another or transformation from one form to another.

So the cycle which demonstrate the movement of oxygen will be called as oxygen cycle.
