Concept introduction:
Photosynthesis:
The process of photosynthesis occurs in plants for their survival. In this process carbon dioxide is absorbed from nature and oxygen is released to nature by plants. Sunlight is the main important component for photosynthesis to occur. Here glucose is formed.
Respiration:
Respiration is a biochemical process in which in the cells of organisms energy is evolved due to reaction between oxygen and glucose and by this process carbon dioxide is released along with water and ATP
(c)

Explanation of Solution
The acidity of the sea water is due to presence of dissolved carbon dioxide in the water.
On the upper sea level there are plants and also on upper level of sea sunlight can enter. As a result of that on the upper level of sea photosynthesis occurs and according to the process of photosynthesis carbon dioxide is taken up by plants. This results a decrease in the dissolved carbon dioxide concentration in the upper sea level.
But still due to the respiration by the sea animals and the plants at upper level there will be some amount of dissolved carbon dioxide in the upper level. So sea water at upper level is acidic but less in amount.
However, in deep sea level,
Hence, deep sea water has a higher acidity the value of
