What are the diseases caused by parasites?
Examples of parasitic diseases that can be bloodborne include African trypanosomiasis, babesiosis, Chagas disease, leishmaniasis, malaria, and toxoplasmosis. In nature, many bloodborne parasites are spread by insects (vectors), so they are also referred to as vector-borne diseases.
What symbiotic relationships do protists have?
Photosynthetic protists serve as producers of nutrition for other organisms. Protists like zooxanthellae have a symbiotic relationship with coral reefs; the protists act as a food source for coral and the coral provides shelter and compounds for photosynthesis for the protists.
