Question

Nutritional eutrophication can cause bloom in which of the following populations?

• A. Phytoplankton
• B. River reeds
• C. Salmon
• D. Water fleas

Answer 1

The correct option is A Phytoplankton

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 a 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.

So the correct option is 'Phytoplankton'.
