Question

The number of common characters and the number of species _________ from Kingdom to Species.

• A. remains constant
• B. decreases and increases, respectively
• C. increases and decreases, respectively
• D. decreases

Answer 1

The correct option is C increases and decreases, respectively

There are seven obligate categories in taxonomic hierarchy: Kingdom, Phylum or Division, Class, Order, Family, Genus and Species. As we go from Kingdom towards Species, the number of similar characters increases. For example, organisms in a genus will have more common characters than all the organsims in a Kingdom. Also, when we go from Kingdom to Species, the number of organisms decreases. For example, there are far more organisms in the animal kingdom than in a single genera.
