True or false: tap water might have fallen from the sky as rain water

the correct answer would be b. i would expect to find higher oxygen and lower carbon dioxide concentrations in the epipelagic zone because this is the well-lit zone in which photosynthesis occurs.

the epipelagic zone refers to the surface layer of the ocean and thus, it receives plenty of sunlight.

due to ample amount of sunlight the rate of photosynthesis would be high and thus, the amount of oxygen produced would be high.

in addition, the amount of oxygen consumed in cellular respiration is less than the amount of oxygen released by photosynthesis.

thus, the amount of oxygen would be high and that of carbon dioxide would be less in epipelagic zone.
