When looking at classification information, you see two organisms belong to the same order. This means they must also belong to
Dvinal [7]

Answer:

What are the options?

The answer can be Kingdom, Phylum, or Class. (If it's multiple choice). But if it's a free response question, then put them all.

Explanation:

The order of classification:

Kingdom

Phylum

Class

Order

Family

Genus

Species

Species is the most specific classification and Kingdom is the least specific. Therefore, if 2 organisms are in the same species, they are also in the same Kingdom, Phylum, Class, Order, Family, and Genus. The same concept applies for Order. If two species are in the same order, then they are automatically in the same Kingdom, Phylum, and Class.
