Detailed explanation-1: -Plant-like protists such as green algae, euglenoids produce almost one-half of the oxygen on the planet through photosynthesis. Other protists decompose and recycle nutrients that humans need to live. All protists make up a huge part of the food chain.

Detailed explanation-2: -Protists that live in the ocean are plant-like plankton, known as algae. These algae are unicellular organisms such as diatoms and dinoflagellates. These organisms contain chloroplasts in their cell, like plants. In turn, they produce oxygen.

Detailed explanation-3: -Photosynthetic protists have chloroplasts and are capable of photosynthesis, although not all use the same chloroplast pigments and they often have different chloroplast structure. Heterotrophic protists require organic chemicals from their environment.

Detailed explanation-4: -Photosynthetic protists are eukaryotic organism that mainly contains chloroplast and prepare their own food. These are unicellular and possess flagella for movement. Euglenoids, diatoms and dinoflagellates are examples of photosynthetic protists.
