Figure 3 the five kingdoms of life this view represents earthly life as composed of 5 kingdoms, 4 of which are eukaryotic, and the 5th, the monera (what we now call prokaryotes) at the base of the treethis view of life is based on structural and functional analyses of organisms, and a proposed evolutionary line in which life moved from simple to more complex, and smaller to larger. Nasa -- larger image most known earth-type life depends on six essential elements (carbon, hydrogen, oxygen, nitrogen, sulfur, and phosphorus) and the presence of liquid water, which is often described as simply carbon-based life.
