5. Which best explains why there is a greater concentration of oxygen
located near the ocean's surface?
A Sunlight warms the ocean's temperature and stimulates oxygen
production near the surface.
B. Plankton produces excess amounts of nutrients that remove oxygen
levels from the atmosphere.
C. Marine life gives off oxygen instead of carbon dioxide, which makes
the ocean water rich in oxygen.
D. Plants, which release oxygen, live near the surface of the ocean,
where they receive large amounts of sunlight.

D. Plants, which release oxygen, live near the surface of the ocean,

where they receive large amounts of sunlight.

Explanation:

Plants are the multicellular and eukaryotic organisms which are autotrophic in nature. Autotrophic means they are able to prepare their own food in the process of photosynthesis. Stomata opens in daytime due to the presence of sunlight through which carbondioxide gas enters into the leaves through stomata and water is absorbed from the soil through roots. These two substances are the reactants of this process. When they combine with each other forming oxygen and glucose.
