Question

The excessive discharge of fertilizers into water bodies results in

• A. Growth of fish
• B. Death of hydrophytes
• C. Eutrophication
• D. Silt

Answer 1

The correct option is C Eutrophication

The rain drains the fertilisers from the soil into nearby water bodies. The presence of extra nutrients brings about the dense growth of plant and animal life. The phenomenon is called eutrophication. Eutrophication leads to organic loading, depletion of oxygen, the death of animals and fouling of water.

So, the correct answer is option C.
