ANIMAL PLANET
VITAL FUNCTIONS• There are vital functions that chracterise all living
things.
• NUTRITION
• INTERACTION
• REPRODUCTION
NUTRITION• Some living things (like human and animals) get their
food by eating other living things.
• They can be clasifiied into three groups:
• HERBIVORES: They only eat plants. ZEBRAS.
• CARNIVORES: they eat other animals. LEOPARDS
• OMNIVORES: they eat other animals and plants.
MONKEYS.
• However, plants are able to make their own food.
INTERACTION• We receive information from the world through our
senses. Then, we make decisions.
• For example, when we are cold, we put on a
jumper.
• Acting and reacting to the wrold around us is
known as INTERACTION.
REPRODUCTION• Lions can give birth to lion cubs, and plants can use
their seeds to make new plants.
• There are different types of reproduction:
• OVIPAROUS – Ducks are born from eggs.
• VIVIPAROUS- Urchins give birth to their young.
• SEEDS- Beans are born from seeds.
VERTEBRATES
VERTEBRATES• All vertebrates have an internal skeleton that is
made up of many bones.
• Some vertebrates are viviparous. (dogs and human
veings)
• Other vertebrates are oviparous (frogs, eagles and
lizards)
BODY PARTS OF VERTEBRATES
• Commonly the bodies of vertebates can be split
into:
• HEAD
• BODY
• LIMBS
INVERTEBRATES
Some animals don’t haveskeletons. They are INVERTEBRATES.
INVERTEBRATES
• All invertebrates have one thing in common: they
are OVIPAROUS
• They aren´t VIVIPAROUS
Invertebratesdon’t have a backbone.
ARTHROPODS• Arthropods is the biggest and most important
group of invertebrates.
• All arthropods have an external skeleton that
protects their body.
• They also have many legs.
This group can be divided into three subgroups:
-insects (six legs)
-arachnids (eight legs)
-crustaceans (ten legs)
INSECTS• It is the largest group of arthropods.
• Their body is divided into three parts: HEAD, THORAX
AND ABDOMEN.
• They have two antennae and may have wings.
Insects are invertebrates.

cockroach fly mosquito
ARACHNIDS• Their body is divided into two parts: Cephalothrax
and abdomen.
• Arachnids don´t have antennae or wings.
CRUSTACEANS• Their body is divided into two parts:
• Cephalothorax and abdomen
• They have two antennae but don´t have wings.
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 holes known as pores.
• Food and water enter their body through these
pores
JELLYFISH• Jellyfish can be very dangerous animals.
• They have poisonous tentacles that they use to hunt
other animals.
ECHINODERMS• Starfish and sea urchins are echinoderms.
• They have many small feet that they use to move
along the bottom of the ocean.
• SEA URCHIN STAR FISH
WORMS• Worms have a long soft segmented body that is
made up of rings.
• Some worms live in the ground, while other live in
water.
MOLLUSCS• All moluscs have soft muscular bodies that they use
to move around the ground or through the water.
• There are three types of mulluscs that have shells:
• Molluscs with two shells. MUSSEL
• Molluscs with one shell. SNAIL
• Molluscs with an internal shell. SQUID
REVIEW • All living things have three vital functions in order to
grow and live. These are: nutrition, interaction and
reproduction.
REVIEW• Animals eat food to get energy. Carnivores only eat
meat and hervivores only eat plants. Omnivores eat
both meat and plants
REVIEW• Some animals give birth to their young and others
lay eggs.
REVIEW• Animals with bones are called vertebrates and
animals without bones are called invertebrates.
Some animals have an external skeleton known as
a shell.
REVIEW• The biggest groups of invertebrates are arthropods..
They can be classified into three groups: arachnids,
crustaceans, and insects. Each of these groups has
a different number of legs.
REVIEW• There are other groups of invertebrates that live in
water. They are jellyfish, molluscs, sponges,
echinoderms and worms.
TRUE OR FALSE?• Spiders are arthropods because they have an external
skeleton and many legs. TRUE
• All vertebrates aren oviparous. FALSE
• Frogs are vertebrates because they have a backbone
and an internal skeleton. TRUE
• All invertebrates are oviparous. TRUE
• Arthropods have an external skeleton and many legs.

LET´S PLAY A GAME• WHAT ANIMAL IS IT?
• YOUR ARE AN
ANIMAL THAT LIVES
AT THE BOTTOM OF
THE SEA. YOU
CANNOT MOVE
BECAUSE YOUR
FIXED TO THE
GROUND. YOUR
BODY IS FULL OF
PORES.

animal. You have
poisonous tentacles
that you use to defend
yourself.
What animal is it? • You are a molluscs with
one shell.
WHAT KIND OF ARTHROPOD ARE YOU?

ARTHROPOD
AND ANSWER
THESE
QUESTIONS:
