Why does the increased level of nutrients (or fertilizers) in the lake water affect the survival of aquatic organisms (like fish)?
ScienceClass 8ICSEAnswered 28 Mar 2026
Answer
Some ponds or lakes have a lot of green algae growing in them. This is caused due to the excessive quantity of chemicals which are washed from the fields. This decreases the oxygen content in the ponds and kills the living organisms in the ponds.
