Detailed explanation-1: -Photosynthetic protists serve as producers of nutrition for other organisms. Protists like zooxanthellae have a symbiotic relationship with coral reefs; the protists act as a food source for coral and the coral provides shelter and compounds for photosynthesis for the protists.

Detailed explanation-2: -They are producers just like plants are. They take in the sun’s energy and use it to make food through photosynthesis. These plant-like protists are also known as algae, which has a green pigment(many other colors also).

Detailed explanation-3: -Many protists, such as algae, are photosynthetic and are vital primary producers in ecosystems, particularly in the ocean as part of the plankton.

Detailed explanation-4: -Autotrophic protists or protist producers are mostly Algae protists: green algae, brown algae, red algae, dinoflagellates, diatoms, and Euglena.
