How are protists a food source for other organisms?
Protists as Food Sources Protists are essential sources of nutrition for many other organisms. In some cases, as in plankton, protists are consumed directly. Alternatively, photosynthetic protists serve as producers of nutrition for other organisms by carbon fixation.
Which is the most diverse kingdom of protists?

What kind of organisms live in fresh water?
In bodies of fresh water, we find unicellular organisms known as protists. Some are easy to see, such as clumps of algae. However, many are microscopic. Learn more about common freshwater protists in this lesson.
Protists as Food Sources Protists are essential sources of nutrition for many other organisms. In some cases, as in plankton, protists are consumed directly. Alternatively, photosynthetic protists serve as producers of nutrition for other organisms by carbon fixation.
Which is a characteristic of a photosynthetic protist?
Photosynthetic protists (photoautotrophs) are characterized by the presence of chloroplasts. Other protists are heterotrophs and consume organic materials (such as other organisms) to obtain nutrition.
How are protists different from other eukaryotes?
Protists include the single-celled eukaryotes living in pond water ([Figure 1]), although protist species live in a variety of other aquatic and terrestrial environments, and occupy many different niches. Not all protists are microscopic and single-celled; there exist some very large multicellular species, such as the kelps.
How are protist parasites harmful to other organisms?
Many protists are pathogenic parasites that must infect other organisms to survive and propagate. Protist parasites include the causative agents of malaria, African sleeping sickness, and waterborne gastroenteritis in humans. Other protist pathogens prey on plants, effecting massive destruction of food crops.
