What is the significance of dissolved oxygen in water?

• A. Reduces pollutants
• B. Essential for the survival of aquatic organisms
• C. Increases water temperature
• D. Promotes the growth of algae

Answer: (B)

Dissolved oxygen is crucial for the survival of aquatic organisms, including fish, invertebrates, and microorganisms. These organisms rely on oxygen dissolved in water for their respiration, which is necessary for their growth, reproduction, and overall health. An adequate concentration of dissolved oxygen is vital for maintaining the balance of aquatic ecosystems, as low levels can lead to hypoxia, resulting in the death of fish and other aquatic life. This highlights the importance of monitoring and maintaining dissolved oxygen levels in any aquatic habitat to ensure the wellbeing of its inhabitants.
