Archaea, Eubacteria, and Eukaryota
The three major groups of photosynthetic organisms are plants, algae, and cyanobacteria. Plants include a wide range of species from mosses to trees, algae encompass diverse forms such as seaweeds and diatoms, and cyanobacteria are single-celled prokaryotic organisms capable of photosynthesis.
The three major subdivisions of all organisms are Archaea, Bacteria, and Eukarya. These groups are based on differences in cell structure and biochemistry. Eukarya includes organisms with complex cells, such as plants, animals, fungi, and protists, while Archaea and Bacteria consist of simpler organisms with prokaryotic cells.
The highest level of classification, domain, has the least variety of organisms, encompassing only three major groups: Bacteria, Archaea, and Eukarya.
Taxonamy
The three classification groups shared by all four organisms are domain, kingdom, and phylum.
The three major groups of parasites are protozoa, helminths (worms), and ectoparasites. Protozoa are single-celled organisms that can infect various parts of the body, helminths are multicellular worms that can be either roundworms or flatworms, and ectoparasites are organisms that live on the body's surface, such as lice or ticks.
Autotrophs and Hetrotrophs.

Protists are a diverse group of eukaryotic organisms that do not fit into the plant, animal, or fungi kingdoms. They are unicellular or simple multicellular organisms that can be autotrophic or heterotrophic. Major groups such as plants, animals, and fungi are more complex multicellular organisms with distinct structures and functions.
The word for the three major subdivisions of all organisms has six letters and ends with n is domain.
