Final answer:
In the hierarchical Linnaean system of biological classification, an order includes more species than a family, which comes lower in the hierarchy.
Step-by-step explanation:
Under the Linnaean system of biological classification, an order includes more species than a family. The hierarchy of biological taxa, from the most inclusive to the most specific, is domain, kingdom, phylum, class, order, family, genus, and species. The system is such that each level includes all the categories below it. The order is higher up the hierarchy than the family and therefore includes a greater number of species. For example, the order Carnivora includes families such as Ursidae (bears), Felidae (cats), and Canidae (dogs), demonstrating that an order encompasses multiple families, each with potentially many species.
