Nuisance Blooms

Question

Nuisance blooms
A) Have become more frequent in recent years
B) Are dominated by dinoflagellates only
C) Are dominated by phytoplankton that lack resting stages
D) Are only associated with turbulent and well mixed water columns

Accepted Answer

Nuisance blooms have indeed become more frequent in recent years, largely due to factors such as nutrient pollution from agricultural runoff and climate change. Choices B, C, and D are incorrect because nuisance blooms can be caused by a variety of organisms, not just dinoflagellates, can include phytoplankton with resting stages, and can occur in various water column conditions, not just turbulent and well-mixed ones.
