Hello YOU!
Explanation:
Phrenology was a science of character divination, faculty psychology, theory of brain and what the 19th-century phrenologists called "the only true science of mind."Phrenology came from the theories of the idiosyncratic Viennese physician Franz Joseph Gall (1758-1828).
Gall believed that the bumps and uneven geography of the human skull were caused by pressure exerted from the brainunderneath. He divided the brain into sections that corresponded to certain behaviors and traits that he called fundamental faculties. This is referred to as localization of function.
Phrenology is considered pseudoscience today, but it was actually a vast improvement over that era's prevailing views of personality. ... But phrenology may be undergoing a redemption of sorts. Not the skull part—that's still considered bunk.
Phrenology was particularly popular in the U.S. because it fit so well with the idea of the American dream–the notion that we can accomplish our goals despite a humble heritage. Spurzheim believed that the brain was like a muscle that could be exercised.

<h3>What are protozoans?</h3>
Protozoans are microorganisms. They are eukaryotic organisms, and they can be parasitic or free-living. They feed on dead and decay matter. Examples are amoeba, euglena, paramecium, etc.
Organisms that eat dead or decay matter are called decomposers. They clean the environment by eating the debris or decay, matter. Microorganisms like bacteria or protozoans are decomposers.
Thus, protozoans are decomposers as they feed on dead and decay matter.
