<span>Protists can be unicellular, colonial or multicellular. Each type of protist has its own phylums or divisions. Protozoans are animal-like. Bacteria and other one-celled organisms are typical prey for a protozoa. Some examples of a protozoa are mosquitoes and amoeba. Algae are photosynthetic and are grouped into divisions depending on pigment similarities. A few examples of algae are sea lettuce and kelp. Fungus-like protists are often brightly colored and get their nutrition by absorbing nutrients from their environment.</span>
