How do protists obtain energy?

Best Answers

They do so by absorbing light and heat from the sun's rays, which combines with water in their vascular systems to form glucose, which is a type of sugar that protists use for energy. Most protists that perform photosynthesis live on land, although several sea-dwelling species use this tactic too. read more

they obtain nutrients by means of phagocytosis, or cell eating, which is considered a form of heterotrophy. Also, since protists include algae, they are autotrophic meaning that they synthesize their own energy from nonliving sources, such as the sun. read more
