Question

the concentration of carbon dioxide in surface water is low, whereas the concentration of oxygen is high because of the
multiple choice
difference in solubility of the gases
exchange of gases between the atmosphere and the ocean
photosynthesis process
respiration of plants and animals
conversion of carbon dioxide to bicarbonate

Explanation:

In surface - water, plants perform photosynthesis. During photosynthesis, carbon dioxide is consumed and oxygen is released. This leads to low carbon - dioxide and high oxygen concentrations. Gas solubility differences do not fully explain the pattern. Gas exchange between atmosphere and ocean is not the main reason for this specific concentration pattern. Respiration of plants and animals consumes oxygen and releases carbon dioxide, which is the opposite of what is observed. Conversion of carbon dioxide to bicarbonate is not the primary cause of the observed concentration differences.

Answer:

C. photosynthesis process
