Use Whittaker method to classify bacteria, protozoa, fungi, alge, prokaryotic and eukaryotic microbes??

Answer:
Explanation:During the late twentieth century, Robert Whittaker's five-kingdom system was a standard feature of biology textbooks, serving as an important organizing scheme for discussing biodiversity. Even as its popularity waned at the end of the century, vestiges of Whittaker's thinking continued to be found in textbooks. Beginning with the germ of an idea in 1957, Whittaker significantly revised his concept in a series of articles published during the subsequent decade. He started with a three-kingdom system that challenged the traditional plant–animal dichotomy, quickly proposed an alternative four-kingdom system, and arrived at his well-known five-kingdom system only after a decade of critical reflection. At last, Whittaker had crafted a system that biologists and educators found attractive because it seemed to capture fundamental properties of living organisms. At its roots, the five-kingdom system was an ecological idea, but Whittaker increasingly relied on cell biology—particularly, the distinction between prokaryotes and eukaryotes—as a central organizing principle for later versions of his system. Thus, the five-kingdom system reflected important intellectual developments in biology during the post–World War II era. Equally important, the success of Whittaker's system owed much to changes in the institutional structure of biology and in science education during the Cold War. Although some of Whittaker's ideas eventually fell victim to molecular systematics, cladistics, and other recent biological developments, the persistence of his system testifies to its broad appeal.
