Expert Answer:

The primary source of oxygen in water bodies is from microscopic algae or submerged plants. In the presence of sunlight, these produce oxygen through photosynthesis and release this oxygen into the pond water, thus providing oxygen for the fish and other organisms in the pond. In the absence of algae, the fishes will be deprived of oxygen and may not be able to survive.
