Explanation: The correct ascending order in taxonomy is: Kingdom, Phylum, Class, Order, Family, Genus, Species. This sequence is the standard hierarchical arrangement described in NCERT biology for animals. Each level becomes more specific from broad grouping (Kingdom) to the most specific (Species).
🧠 Did You Know? Each level shares common characteristics; for example, organisms in the same phylum share fundamental body plans, while those in the same species can usually interbreed.
💡 NCERT Memory Line: King Philip Came Over For Good Soup (Kingdom, Phylum, Class, Order, Family, Genus, Species).
