How does the Classification system distinguish between organisms?

By organising them into five major kingdoms and further dividing each kingdom into phyla (or divisions), classes, orders, families, genus, and species.

Explanation:

Organisms that share the most similar features are grouped into the same species. Species with similar features fall under the same genus. Several genus make up a family, several families make up an order, several orders make up a class, several classes make up a phylum (or division), and several phyla (or divisions) make up a kingdom.

Note: there are three domains (or superkingdoms): Archea, Bacteria, and Eukarya.
