Question

Arrange the following taxonomic categories in ascending order.

(a) Genus
(b) Class
(c) Order
(d) Phylum
(e) Family
(f) Kingdom
(g) Species

Choose the correct answer from the options given below:

Accepted Answer

B. 1. **Ascending order** means starting from the smallest, most specific taxonomic category and moving toward the largest, most general one.

2. Recall the standard taxonomic hierarchy taught in classification: Species → Genus → Family → Order → Class → Phylum → Kingdom.

3. Species (g) is the smallest and most specific unit, so it comes first.

4. Several similar species are grouped into a Genus (a); several related genera form a Family (e).

5. Related families are grouped into an Order (c); related orders form a Class (b).

6. Related classes are grouped into a Phylum (d), and finally, related phyla are grouped into a Kingdom (f), the broadest category.

7. So the correct ascending sequence is:
Species (g) → Genus (a) → Family (e) → Order (c) → Class (b) → Phylum (d) → Kingdom (f).

8. Hence, the answer is **B**.
