3. Recognize that protozoa are single-celled eukaryotes without a cell wall, typically motile, and not classified as molds or yeasts.
4. Note that archaea are prokaryotic microorganisms distinct from bacteria, often found in extreme environments, and are not molds or yeasts.
5. Conclude that molds and yeasts belong to the group called fungi, which are eukaryotic organisms distinct from bacteria, archaea, and protozoa.
