None of the above.
Diatoms belong to the Kingdom Protista and the phylum Bacillariophyta

Diatoms belong to the phylum Chrysophyta and dinoflagellates belong to the phylum Pyrrophyta (see the classification summary). Diatoms are single-celled
autotrophs requiring sunlight and cold nutrient-rich water. Their silicaimpregnated cell walls form a hard, rigid, transparent covering (frustule). Cells are yellow brown from the pigment fucoxanthin and produce oil droplets that contribute to their buoyancy. Dinoflagellates are single-celled organisms with both autotrophic and heterotrophic abilities. Their cell walls may be smooth or armored with cellulose plates, they range from green to red in color, and they have flagella allowing them limited mobility. Dinoflagellates are responsible for much bioluminescence and many red tides. Euphausids and copepods are crustacea belonging to the phylum Arthropoda (see the classification summary). Copepods are herbivores and are smaller and shorterlived than euphausiids. Euphausiids, or krill, are mainly herbivores but also consume small zooplankton. Both are heterotrophs.
