An important difference between cellular respiration and photosynthesis is that when cellular respiration begins, glucose molecules are split. However, when photosynthesis begins

-ADP molecules are split.
-water molecules are split.
-oxygen molecules are split.
-carbon dioxide molecules are split.

Of seawater increases with decrease in the temperature. therefore, the cold water sinks to the deeper layers at the bottom
