Question

The so-called "red tide" is generally caused by which of the following organisms?
A)Lichens
B)Bacteria
C)Pfiesteria
D)Dinoflagellates

Accepted Answer

Red tide is generally caused by dinoflagellates, which are single-celled marine organisms that are capable of producing toxins. These toxins can accumulate in shellfish and other marine organisms, making them unsafe for human consumption. The red tide gets its name from the fact that the dinoflagellates responsible for it often give an intense red color to the water.
