Question

A group of classes forms a/an​

Answer 1

A group of classes forms a phylum.

Explanation:

A system of categorising organisms according to a hierarchy of taxonomic levels is known as hierarchical classification. There are seven taxonomic levels

1. Kingdom

2. phylum

3. class

4. order

5. family

6. genus

7. species.

As you advance up the taxonomic ladder, the classifications get more generic.

For example, Human sapiens can be classified as

Kingdom: Animalia

Phylum: Chordata

Class: Mammalia

Order: Primates

Family: Hominidae

Genus: Homo

Species: sapiens
