Which of the following statements regarding eutrophication are correct ? (i) Eutrophication is the natural ageing of a lake by nutrient enrichment of its water. (ii) Pollutants from human activities like effluents from the industries and homes can radically accelerate the aging process of a lake. This phenomenon is called as cultural or accelerated eutrophication. (iii) The plant nutrients responsible for eutrophication are nitrates and phosphates. (iv) These phosphates and nitrates accelerate the growth of algae, which utilise oxygen and may deoxygenate the water to kill the fish and other aquatic animals.

Increase in the population of decomposing bacteria in a water body kills the aquatic life because of:

Explain how does the inflow of large amount of nutrients like phosphates and nitrates into the water body drastically affects the aquatic life there. Name the phenomenon responsible.

Assertion: The prime contaminants of the eutrophic water body are nitrates and phosphates which acts as plant nutrients. Reason: They overstimulate the growth of algae, fishes and other aquatic animals and robbing the water of dissolved oxygen.

Agricultural outflows contains phosphate fertilizers leads to (A) Enhaced growth of algae in rivers (B) Decrease in the amount of dissolved oxygen in water (C) Increase in fish pollution The correct answer is
