Question

Animals, Dogs, and mammals represents?
A. Taxa at different levels
B. Taxonomic hierarchy
C. Taxa at an equivalent level
D. Categories at an equivalent level

Answer 1

Hint: Animals refer to members of the Animal Kingdom. Dogs are carnivore mammals. Mammals are representatives of the vertebrate class Mammalia.

Complete answer: Linnaeus' hierarchical system of classification consists of seven levels called taxa. They are, from largest to smallest, Kingdom, Phylum, Class, Order, Family, Genus, Species. The Kingdom is the largest and most inclusive of the taxonomic categories.
Animals, dogs, mammals –these three appear to be very similar, but yet they are different.
1. When we say ‘animal’ we tend to refer to the members of the animal kingdom (Kingdom Animalia).
2. Dogs are also animals, so are mammals.
3. When we say mammals, we refer to the Vertebrate class ‘Mammalia’.
4. Dogs are carnivorous mammals too (Order Carnivora).
5. So what are these ‘class’, ‘kingdom’, and ‘order’…?
6. These are basic terms used in classification or more appropriately systematics.
7. Each category of classification is known as a taxon and its plural form is taxa.
8. It is just a representation of a rank.
10. So, Animals, dogs, and mammals represent different levels of taxa.

So, the correct option is A. Taxa at different levels

Note: When there are so many diverse species out there, an arrangement should be there to identify them specifically. That is why taxonomy, systematics, classification –all these came into the view but they are different subjects with different definitions.
