1. How living things are Grouped
Chapter 2

2. Classification
Living things are grouped according to their similarities.
The living things are grouped into five major groups called kingdoms:
Animals
Plants
Bacteria
Fungi
Protists

3. Kingdoms

4. Smaller Groups
The Kingdoms are then broken down into smaller groups until you reach an actual species
Kingdom
Phylum
Class
Order
Family
Genus
Species

5. Levels of Classification

6. Plants Plants are broken down a little differently.
The first level would be vascular or non vascular
Then whether or not they make seeds
Then whether they produce flowers or cones

7. Vertebrates Vertebrates are animals that have a backbone.
They are classified into five phyla:
Fish- scaly skin, must live in water
Birds- have feathers but may or may not fly
Amphibians- smooth skin; must begin life in water
Reptiles- scaly skin; cold blooded
Mammals- have fur; produce milk for their young

8. Invertebrates Invertebrates are animals without backbones.
These animals generally have a hard shell outside their body called an exoskeleton.
As they grow, they must replace the shell.

9. Classes of invertebrates
Simple- includes earthworms and sponges
Mollusks- includes squid, octopus, snails, clams, and oysters

10. Arthropods
Arthropods are known for their jointed bodies and hard exoskeletons.
Crustaceans are one example of arthropods.
The arthropod phyla is divided into several subgroups.
Let’s explore those groups now!

11. Crustaceans
The crustacean group is a group of arthropods that have claws.
If you like seafood, I bet you know some of these.

12. insects Insects are another group of arthropods.
They are characterized by having six legs.

13. Arachnids
Arachnids are another form of arthropods. They have eight legs.
