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.

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.

What animal is it?• You are a dangerous

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?

• THINK OF AN

ARTHROPOD

AND ANSWER

THESE

QUESTIONS:

• - Do you have wings?

cephalothorax?

• How many legs do you

have?

body divided into?
