• A. Have no effect
• B. Cause spurt in population of primary consumers
• C. Cause rapid growth of algae
• D. Affect the food chain

Answer 1

The correct option is D Affect the food chain

The food chain is the series or linear link of different organisms through which the nutrients flow from one level to another. The phytoplanktons are the major producers in the aquatic ecosystem. When the phytoplanktons are destroyed, there will be no producers and no food available for the consumers. This will affect the food chain.

Thus, the correct answer is option D.
