مندرجہ ذیل میں سے کون سی طحالب سرخ لہر کے لیے ذمہ دار ہے۔
Explanation

The name “red tide” comes from the fact that the overgrowth of algae can cause the colour of the water to turn red.

The red tides caused by the dinoflagellate Gonyaulax (unicellular algae) are serious

because this organism produces powerful toxins (saxitoxin and gonyautoxins) that can kill aquatic organisms.
