Let’s solve this step by step.
We are given a diagram that shows levels of biological classification, from the most specific (top) to the most general (bottom). Each level has a name next to it — like *Canis lupus*, *Canis*, *Canidae*, etc. — and we need to match each blank with the correct term from the box:
Order, Class, Phylum, Domain, Genus, Species, Kingdom, Family
---
Step 1: Understand the hierarchy
In biology, organisms are classified in this order (from broadest to most specific):
Domain → Kingdom → Phylum → Class → Order → Family → Genus → Species
But in the diagram, it goes
from top (most specific) to bottom (broadest), so we’ll go backwards:
Top = Most Specific → Bottom = Most General
So let’s list them in reverse order for matching:
1.
Species – most specific (e.g., *Canis lupus* = dog)
2.
Genus – group of related species (e.g., *Canis* includes dogs, jackals)
3.
Family – group of related genera (e.g., Canidae = foxes, dogs, jackals)
4.
Order – group of families (e.g., Carnivora = cats, dogs, foxes, etc.)
5.
Class – group of orders (e.g., Mammalia = mammals)
6.
Phylum – group of classes (e.g., Chordata = animals with backbones)
7.
Kingdom – group of phyla (e.g., Animalia = all animals)
8.
Domain – broadest category (e.g., Eukarya = organisms with complex cells)

Step 2: Match each level in the diagram
Starting from the TOP:
🔹 First box: next to *Canis lupus* → This is the
species name →
Species
🔹 Second box: next to *Canis* → This is the
genus →
Genus
🔹 Third box: next to *Canidae* → This is the
family →
Family
🔹 Fourth box: next to *Carnivora* → This is the
order →
Order
🔹 Fifth box: next to *Mammalia* → This is the
class →
Class
🔹 Sixth box: next to *Chordata* → This is the
phylum →
Phylum
🔹 Seventh box: next to *Animalia* → This is the
kingdom →
Kingdom
🔹 Eighth box: next to *Eukarya* → This is the
domain →
Domain

Final Check:
Let’s write them in order from top to bottom:
1. Species
2. Genus
3. Family
4. Order
5. Class
6. Phylum
7. Kingdom
8. Domain
That matches the standard taxonomic ranks — perfect!

Final Answer:
From top to bottom, the labels are:
Species, Genus, Family, Order, Class, Phylum, Kingdom, Domain
