Answer 1

oxygen dissolved in water is imp. for survival becuse aquatic species have gills so they can take dissolved oxygen easily in process of respiration
I hope my answer helps you.

Answer 2

Answer:

• Dissolved oxygen (DO) is one of the most significant water quality indices. It is vital for fish and other aquatic organisms to survive.
• Due to aerating action of winds, oxygen dissolves in surface water.
• Oxygen is also implemented as a by-product of photosynthesis of aquatic plants in water.

Oxygen reaches water by two natural procedures:

1. Atmospheric diffusion and
2. Aquatic plant photosynthesis.

• The mixing of surface waters by wind and waves improves the rate of dissolution or absorption of oxygen from the atmosphere into the water.
