Assertion: Higher levels of dissolved oxygen indicate better water quality.
Reasoning: Dissolved oxygen (DO) is a measure of the amount of oxygen available in water for aquatic organisms to breathe. Higher levels of DO indicate that there is more oxygen available for aquatic organisms to use, which indicates better water quality.

Both assertion and reasoning are false.
Answers (1)
Dissolved oxygen is an essential parameter to assess the water quality of aquatic environments. The level of DO in water indicates the amount of oxygen available for aquatic organisms to breathe, which is necessary for their survival. Therefore, higher levels of DO are generally associated with better water quality.
The reasoning provided in the assertion is accurate and explains why higher levels of DO indicate better water quality. When DO levels are low, aquatic organisms may become stressed or die due to a lack of oxygen, indicating poor water quality. Therefore, the higher the level of DO, the more suitable the aquatic environment is for sustaining life.
In conclusion, both the assertion and reasoning are true, and the reasoning correctly explains the assertion.
