Explanation:
In an ocean ecosystem, many types of fish and turtles are herbivores that eat algae and seagrass. Sea urchins are powerful primary consumers in kelp forests.
The answer can be either multicellular organisms or the scientific word of Eukaryotes.
The common characteristic of those two organisms is hard spherical shells (exoskeleton).
Foraminiferans are single cell marine eukaryotes divided into granular endoplasm and transparent ectoplasm. Foraminiferans are enveloped with tests, hard shells, usually composed of calcium carbonate (sometimes from organic compounds or silica).
Coccolithophore is a unicellular, eukaryotic alga with special calcium carbonate plates (or scales) of uncertain function (coccoliths). Each unicellular alga is enclosed in its own collection of coccoliths, the which make up its exoskeleton- coccosphere.
