Question

The need for energy, gained by respiration and photosynthesis, is the driving force of the oxygen cycle. Please select the best answer from the choices provided T F

Answer 1

The answer is T - true.

Answer 2

Answer: True

Step-by-step explanation: Oxygen cycle is the process by which oxygen is released into the atmosphere by photosynthesis and is used by aerobic organisms while the carbon dioxide is released as a by product of respiration. This carbon dioxide is used in photosynthesis for production of glucose.

`6CO_2+6H_2O\overset{sunlight}\rightarrow C_6H_(12)O_6+6O_2`

Hence, for oxygen to remain in the atmosphere, it has to circulate through various forms of nature and this circulation of oxygen is called as oxygen cycle.
