26
What is the highest category in the classification system of animals?
Kingdom Animalia ## Footnote This category includes all animals belonging to various phyla.
27
What does the Kingdom Plantae comprise?
All plants from various divisions ## Footnote This kingdom is distinct from the animal kingdom.
28
What is the order of taxonomic categories from species to kingdom?
Species, Genus, Family, Order, Class, Phylum, Kingdom ## Footnote These categories are used to classify living organisms.
29
How does the number of common characteristics change as we move from species to kingdom?
The number of common characteristics decreases ## Footnote Lower taxa share more characteristics compared to higher categories.
30
What is the problem associated with higher taxonomic categories?
