Section 1 & 2 - Protists Protists are members of the Kingdom Protista. Some are so tiny that they cannot be seen without a microscope.  Others grow many  meters long. Some are poisonous.  Some provide food for people. Some protists are producers . They make their food by photosynthesis. Some protists are heterotrophs . This is an organism that gets food by eating other organisms or their byproducts. Some protists are decomposers . Some protists are parasites . This is an organism that feeds on an organism of another species (the host) and that usually harms the host. Protists are best described as to what they are not: they are not animals, fungi, or plants. Most protists reproduce asexually. They are identical to the one parent. Some reproduce sexually. This is termed conjugation . This is when two paramecium join together and exchange genetic material. 1
