In a pond oxygen is gathered in two ways. One from the air or from the aquatic plants that live in the pond. Oxygen gets dissolved from these when mixed with air and water movement
Glucose sugar is produced during photosynthesis and is used in cellular respiration. When used in cellular respiration glucose sugar is combined with oxygen to produce Carbon Dioxide (Co2), water (H2o), and energy in the form of ATP
