2. 1 VITAL FUNCTIONS
There are vital functions that characterise living things: 1
NUTRITION 2
INTERACTION 3
REPRODUCTION

3. NUTRITION Living things need energy to do different activities
NUTRITION Living things need energy to do different activities. Energy comes from food. Animals that feed on other living things can be: - Carnivores: they eat other animals (f.e.:leopards) - Omnivores: they eat other animals and plants (f.e.: human beings) - Herbivores: they eat plants (f.e.: zebras) Living things that make their own food are: - Trees - Plants 1

4. INTERACTION Interaction = acting and reacting We receive information from around the world through our SENSES. Then we make decisions: For example: if it’s cold, we put a coat on If it’s hot, we go to the swimming pool. 2

5. REPRODUCTION There are different types of reproduction: - Oviparous: they are born from eggs. - Viviparous: they give birth to their young. - Seeds: they are born from seeds. 3

6. 2 ANIMAL CLASSIFICATION1
VERTEBRATES 2
INVERTEBRATES

7. VERTEBRATES They have a backbone.
They have an internal skeleton that is made up of many bones.
Some vertebrates are viviparous (f.e.: dogs or human beings) others are oviparous (f.e.: frogs or lizards)
Nearly all vertebrates have limbs:
Feet
Wings
Fins
feet
wings
fins

8. VERTEBRATES classification
birds
mammals
fish
reptiles
wings
feet
fins
anphibians

9. VERTEBRATES The bear and the horse are viviparous.
The body of a vertebrate can be split into HEAD, BODY and LIMBS.
VERTEBRATES
The main set of bones are joined together making up the backbone.
The internal skeleton supports the body.

10. All invertebrates have one thing in common: they are OVIPAROUS
They don’t have a backbone.
They don’t have an internal skeleton or bones.
All invertebrates have one thing in common:
they are OVIPAROUS

11. INVERTEBRATES classification
arthropods
echinoderms
jellyfish
worms
sponges
molluscs

12. 3 Arthropods butterfly grasshopper
The biggest and most important group of invertebrates are named arthropods.
All of them have an external skeleton that protects their body.
They also have many legs.
ARTHROPODS
INSECTS ARACHNIDS CRUSTACEANS
6 legs legs legs
ant
beetle
ladybird

13. INSECTS FLY Insects are the largest group of arthropods.
Their body is divided into three parts:
Head
Thorax
Abdomen
They have two antennae and may have wings.
wings
legs
head
abdomen
antennae
thorax
INSECTS

14. ARACHNIDS Their body is divided into two parts:
Cephalothorax (head and thorax are together)
Abdomen
They don’t have antennae or wings.
SPIDER
legs
abdomen
cephalothorax
ARACHNIDS

15. The majority of crustaceans have the body divided into two parts:
Cephalothorax (head and thorax are together)
Abdomen
They have two antennae but they don’t have wings.
LOBSTER
legs
abdomen
antennae
cephalothorax
CRUSTACEANS

16. 4 MORE INVERTEBRATES SPONGES
Sponges live at the bottom of the sea. They are fixed to the ground so they cannot move around.
Their body is full of pores.
pores
JELLYFISH
Jellyfish have poisonous tentacles that they use to hunt animals and to defend themselves.
tentacles

17. MORE INVERTEBRATES ECHINODERMS
Starfish
ECHINODERMS
They have many small feet that they use to move along the bottom of the ocean.
Sea urchin
WORMS
Worms have a long soft segmented body made up of rings.
Some of them live in the ground (terrestrial) and other ones live in water (aquatic).
rings

18. MORE INVERTEBRATES MOLLUSCS MUSSEL
Some of them are terrestrial and other ones are aquatic.
They have soft muscular bodies that they use to move.
Nearly all molluscs have a shell.
There are 3 types of mulluscs that have shells:
Molluscs with two shells: f.e.: mussels (their shells are called valves)
Molluscs with one shell: f.e.: snails
Molluscs with an internal shell: f.e.: squid
valves
shell
SNAIL
SQUID

19. QUESTIONS

20. Relate the following actions to the vital function.
Scape from a predator NUTRITION
Laying eggs INTERACTION
Being an omnivore REPRODUCTION

21. Read the sentences and say either VERTEBRATE or INVERTEBRATE
a) They don’t have a backbone.
b) They can lay eggs or give birth to live babies.
c) Their body is divided into three parts.

22. Complete the table: ARTHROPODS BODY LEGS EXAMPLES Insects Two parts

23. Find the odd one out in each group:
Lizard / Frog / Worm / Cat
Fly / Dragonfly / Bee / Grasshopper
Ant / Spider / Beetle / Starfish

24. Look at the animals and say which parts belong to each one:
wing
abdomen
thorax
leg
cephalothorax
head
antennae

25. Read the description below. What animal is it describing?
This animal doesn’t have legs.
It is attached to the ground and it can’t move.
It gets food from water and nutrients that pass
through holes in its body.
It’s a ……………
