1.	Explain accelerated eutrophication. Mention any two consequences of this phenomenon.
Answer» Accelerated eutrophication occurs due to the passage of sewage and run-off from fertilized fields into ponds, lakes and other water bodies. Nutrients present in sewage and fertilizers causes dense growth of plants and planktonic algae. Consequences of accelerated eutrophication : (i) Eutrophic water bodies support excessive growth of floating plants, e.g., water hyacinth is one such plant that sometimes chokes ponds, lakes and rivers. (ii) Due to increase of algal blooms, there is drastic decrease in oxygen replenishment inside water that kills aquatic animals.
