Question

which of the following lists the order of taxonomic levels from the largest to the smallest group?
○ domain, kingdom, class, order, family, phylum, genus, species
○ species, genus, family, order, class, phylum, kingdom, domain
○ class, family, order, domain, kingdom, phylum, genus, species
○ domain, kingdom, phylum, class, order, family, genus, species

Explanation:

To determine the correct order of taxonomic levels from largest to smallest, we recall the standard taxonomic hierarchy: Domain (the broadest group) → Kingdom → Phylum → Class → Order → Family → Genus → Species (the most specific group).

• The first option incorrectly places "phylum" after "family".
• The second option lists levels from smallest to largest (species to domain), which is the reverse of what's needed.
• The third option has a jumbled order (e.g., "class" before "domain" and "kingdom", and "family" before "order").
• The fourth option follows the correct hierarchy: domain (largest), kingdom, phylum, class, order, family, genus, species (smallest).

Answer:

D. domain, kingdom, phylum, class, order, family, genus, species (assuming the last option is labeled D; if the original options had labels like A - D, and the last option is the correct one, the answer would be the last option's identifier and text, e.g., "The fourth option: domain, kingdom, phylum, class, order, family, genus, species")
