Final answer:
The statement that hierarchies only show main ideas without supporting details is false. Hierarchies like the taxonomic classification system do provide supporting details by organizing organisms into progressively specific categories where each sublevel denotes greater similarity.
Step-by-step explanation:
The statement is false. Hierarchies, such as those used in the taxonomic classification system, do not just show the main ideas without the supporting details. Instead, in the hierarchical model for taxonomic classification, from the point of origin, the groups become less specific. Organisms are organized into categories from smaller, more specific ones to larger, more inclusive groups.
At each sublevel of the hierarchy, the organisms grouped together are more similar to one another. For example, within the Animal Kingdom, there are multiple Phyla; within each Phylum, there are Classes, and within each Class, there are Orders, and so on, down to Genus and Species. Species represent the most specific level of the hierarchy, where organisms share many characteristics.
