प्रश्न
What are the sources of dissolved oxygen in water?
उत्तर
The oxygen reaches water through the atmosphere or by the process of photosynthesis carried out by green plants during daytime. But, during night as photosynthesis stops, the plants continue to respire, resulting in the reduction of dissolved oxygen. This dissolved oxygen is even used by microorganisms to oxidize organic matter. The sources of dissolved oxygen in water can be
(i) Photosynthesis by aquatic plants.
(ii) Due to the direct contact of the water surface with air.
(iii) Mechanical aeration.
