Understand the taxonomic hierarchy: The taxonomic system organizes living organisms into a hierarchy of categories. From broadest to most specific, the order is: Domain, Kingdom, Phylum, Class, Order, Family, Genus, and Species.
Analyze the first statement: 'Order is ranked above class.' Based on the hierarchy, this is incorrect because Class is ranked above Order.
Analyze the second statement: 'The domain is the highest taxonomic rank, above kingdom.' This is correct because Domain is indeed the broadest and highest rank in the taxonomic system, encompassing multiple kingdoms.
Analyze the third statement: 'Genus is ranked higher than family.' This is incorrect because Family is ranked higher than Genus in the hierarchy.
Analyze the fourth statement: 'Species is the broadest taxonomic category.' This is incorrect because Species is the most specific category, not the broadest.
