Question

Excessive growth of planktonic algae in nutrient rich water is known as

• A. Eutrophication
• B. Stratification
• C. Guttation
• D. None of the above

Answer 1

The correct option is A Eutrophication

A.Eutrophication or hypertrophication, is when a body of water becomes overly enriched with minerals and nutrients that induce excessive growth of plants and algae. This process may result in oxygen depletion of the water body. One example is the "bloom" or great increase of phytoplankton in a water body as a response to increased levels of nutrients. Eutrophication is almost always induced by the discharge of nitrate or phosphate-containing detergents, fertilizers, or sewage into an aquatic system.

B.Stratification - Placing of seeds in soil in the form of layers to eliminate dormancy and promote seed germination is called Stratification.

C.Guttation - Loss of water in the form of droplets are called Guttation.

So the correct option is 'Eutrophication'.
