How do algal biological activities affect water conditions?

• A. Increase sedimentation
• B. Enhance pH, alkalinity, and dissolved oxygen levels
• C. Decrease temperature of water
• D. Eliminate turbidity

Answer: (B)

The choice highlighting that algal biological activities enhance pH, alkalinity, and dissolved oxygen levels reflects the crucial role that algae play in aquatic ecosystems. During the process of photosynthesis, algae absorb carbon dioxide and release oxygen, leading to increased levels of dissolved oxygen in the water. This increase is vital for the survival of aquatic organisms, particularly fish, which rely on sufficient oxygen levels in the water for respiration. Moreover, the photosynthetic activities of algae can also lead to a rise in pH and alkalinity. When algae consume carbon dioxide, which is a weak acid, the reduction of carbon dioxide in the water increases the pH level, making the water less acidic. This shift in pH can have a significant impact on the aquatic environment, influencing the solubility and bioavailability of nutrients and metals. Ultimately, a healthy population of algae contributes positively to water conditions, benefiting the overall ecology of the system. Understanding the impact of algal activities is essential in water management, especially for operators working to maintain the balance of aquatic environments.
