Question

besides a red tide, what other indicator would tell you that there is a plankton bloom in progress? group of answer choices you would see bioluminescence you would see a sign on the beach telling you not to harvest clams you would see a ton of dinoflagellates under a microscope all are correct

Answer 1

Plankton blooms can be indicated by bioluminescence, advisories against shellfish harvesting, and a large presence of dinoflagellates under a microscope, in addition to a red tide.

Step-by-step explanation:

Indicators of a plankton bloom include not only the presence of a red tide but also other signs such as bioluminescence and closure of shellfish harvesting. Bioluminescence can be especially noticeable when billions of dinoflagellates emitted light and cause ocean waves to twinkle with a blue color. Moreover, during the bloom, authorities may post signs advising against the harvesting of shellfish like clams, as they can accumulate dangerous levels of toxin. Examining water samples under a microscope and seeing a large number of dinoflagellates also indicates a bloom.
