Answer to Question 1

ANS: D
A harmful algal bloom happens when high concentrations of phytoplankton begin to affect nearby
organisms in a negative way. Dinoflagellates are usually the culprits. Some make toxins within their
cells as a by-product of metabolism. This affects marine life through the natural consumption in food
webs. Information can be found in the section Most Phytoplankton are Photosynthetic Autotrophs

Answer to Question 2

ANS: A
The majority of dinoflagellates are free-living, but some are found in the tissues of other organisms.
They have whip-like flagella for minimal movement. Information can be found in the section Most
Phytoplankton are Photosynthetic Autotrophs.
