Question

Which protists are associated with red tides?

a) Diatoms
b) Dinoflagellates
c) Euglenoids
d) Foraminifera

Answer 1

Dinoflagellates are the protists associated with red tides due to the release of toxins that harm marine life and humans who consume affected organisms.

Step-by-step explanation:

Dinoflagellates are the protists associated with red tides. Red tides are population explosions of certain dinoflagellate species during the summer months that can tint the ocean with a muddy red color. These dinoflagellates release an asphyxiating toxin that can harm marine life and humans who consume affected organisms.
