Question

Natural aging of a lake by nutrient enrichment of its water

• A. Eutrophication
• B. Carrying capacity
• C. Photophosphorylation
• D. None of the above

Answer 1

The correct option is A Eutrophication

• When the water body becomes overly riched with minerals and nutrients. This induces the excessive growth of planktonic algae. This phenomenon of excessive growth of planktonic algae in nutrient-rich water is known as eutrophication.
• Due to the excessive growth of planktonic algae the condition of hypoxia is created which leads to the death of aquatic organisms due to low oxygen and slowly results in the disappearance of the lake.

So, the correct answer is 'Eutrophication'.
