Arrange the following taxonomic categories in ascending order.
(a) Genus (b) Class (c) Order (d) Phylum
(e) Family (f) Kingdom (g) Species
Show Hint
Memorize taxonomy using shortcut:
King Philip Came Over For Good Soup
(Kingdom, Phylum, Class, Order, Family, Genus, Species)
Reverse it for ascending order.
Concept:
Biological classification organizes organisms into hierarchical taxonomic categories based on similarities and evolutionary relationships.
Taxonomy follows a fixed hierarchy from smallest category to largest category.
The standard taxonomic sequence is
\[
Species \rightarrow Genus \rightarrow Family \rightarrow Order \rightarrow Class \rightarrow Phylum \rightarrow Kingdom
\]
Ascending order means moving from smallest level toward highest and broadest level.
Step 1: Recall taxonomic hierarchy.
The biological classification system groups organisms systematically.
The smallest taxonomic unit is species because members share maximum similarity.
Above species comes genus, then family, then order.
Higher categories include class, phylum, and finally kingdom.
Thus sequence becomes
\[
Species \lt Genus \lt Family \lt Order \lt Class \lt Phylum \lt Kingdom
\]
Step 2: Convert into given letter sequence.
Given letters:
Species = g
Genus = a
Family = e
Order = c
Class = b
Phylum = d
Kingdom = f
So required order is
\[
(g),(a),(e),(c),(b),(d),(f)
\]
Step 3: Match with options.
Checking options carefully
Option (B) exactly matches required sequence.
Therefore Option (2) is correct.
Step 4: State final answer.
Hence correct ascending arrangement is
\[
Species \rightarrow Genus \rightarrow Family \rightarrow Order \rightarrow Class \rightarrow Phylum \rightarrow Kingdom
\]
Thus
\[
\boxed{\text{Option (2)}}
\]
