Drinking water problem in our urban' areas is caused mainly because we fail to protect our water bodies. Explain how accelerated eutrophication chokes our water bodies to death.

Drinking water problem in our urban areas is caused mainly because we fail to protect our water bodies. Explain how accelerated eutrophicaiton chokes our water bodies to death.

The release of municipal wastewater and industrial waste into our natural water bodies is causing disastrous effect to the aquatic life. Explain the biological treatment that should be given to it before releasing into the natural water bodies.

Which cause death of fish in water bodies polluted by sewage?

How does algal bloom destroy the quality of a fresh water body ? Explain.

Explain how harmful chemicals enter our bodies.

Eutrophication of water bodies leading to killing fishes is mainly due to

A water body characterized by nutrient rich water supports abundant growth of phytoplanktons and other water plants on its surface. Over time, the water body gets filled with a large number of such plants and the process is called Eutrophication. In such water bodies, dissolved oxygen content is nil or very less. In eutrophicated water body, growth rate of phytoplankton is high because of:

Over time, the water body gets filled with a large number of such plants and the process is called Eutrophication. In such water bodies, dissolved oxygen content is nil or very less. There is an extremely low level of dissolved oxygen in a eutrophicated water body because:
