Nuisance growth of aquatic plants and bl...

Nuisance growth of aquatic plants and bloom-forming algae in natural waters is generally due to high concentrations of

A

carbon

B

sulphur

C

calcium

D

phosphorus.

Text Solution

Verified by Experts

The correct Answer is:
D
Phosphorus in the form of phosphates as well as nitrates act as nutrients for the bloom-forming algae. Increased growth of algae because of these pollutants added to water bodies by human activities is called as cultural eutrophication. This literally, chokes the water body and lead to death of the organisms. Decomposition of these algae as well as dead water organisms, further deplete the dissolved oxygen content in water.
