Question

In the taxonomic categories which hierarchical arrangement in ascending order is correct in the case of animals?

• A. Kingdom, Phylum, Class, Order, Family, Genus, Species
• B. Kingdom, Class, Phylum, Family, Order, Genus, Species
• C. Kingdom, Order, Class, Phylum, Family, Genus, Species
• D. Kingdom, Order, Phylum, Class, Family, Genus, Species

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
Taxonomic hierarchy is a multi-level system of classification.
- Ascending order means starting from the most specific (Species) to the most general (Kingdom).
- Descending order means starting from the Kingdom to Species.
Detailed Explanation:
The correct taxonomic hierarchy is:
Species $\rightarrow$ Genus $\rightarrow$ Family $\rightarrow$ Order $\rightarrow$ Class $\rightarrow$ Phylum/Division $\rightarrow$ Kingdom.
Looking at the options:
(1) shows Kingdom $\rightarrow$ Phylum $\rightarrow$ Class $\rightarrow$ Order $\rightarrow$ Family $\rightarrow$ Genus $\rightarrow$ Species. This is the correct hierarchy but in descending order.
Since the question specifically asks for ascending order and none of the options start with Species, the options provided are technically incorrect in their sequence direction. However, if we evaluate for the correct biological sequence irrespective of direction, (1) is the standard correct hierarchy.
Step 2: Final Answer:
While (1) lists the correct biological ranks in sequence, it is in descending order. A truly ascending list would start with Species.
