Question

answer the following.....

Answer 1

Excess fertilizers and pesticides are among the many common pollutants that can degrade water quality.

Fertilizers are made of nutrients, such as nitrogen and phosphorus. When it rains, these nutrients are carried into the nearest river or other water bodies. Too many nutrients in water can cause algae to grow, which uses up the oxygen in the water, this process is called Eutrophication. Low levels of oxygen in water can adversely affect aquatic wildlife and even lead to killing of fish and other aquatic organisms.

Answer 2

Privet Mate...

Here your answer is ......,

⚫ Excessive use of chemical fertilizers and pesticides causes accumulation of nitrates and phosphate salts in the soil, this causes land pollution.

During rains and irrigation, some of these salts are carried into water bodies like lake, rivers, ponds, etc., thereby increasing water pollution.

The presence of these salts in water causes tremendous growth of algae and other organic matter.

It lead to depletion of dissolved oxygen. This process is known as 'Eutrophication'.
