In effect, the thallus is one Trypanosoma brucei and Trypanosoma cruzi are parasites--therefore the ecology of their vector and host is the ecology of the species itself. Combine photosynthesis and heterotrophic nutrition. What two domains contain prokaryotic celled organisms? Mitochondria are present in most of the protists which generates energy to be used by the cells. View the green algae specimens available. Of about 2,400 living species, 83% are marine, and nearly a half are photosynthetic (Saldarriaga & Taylor, 2017).
