ANIMAL PLANET
![Page 2: Animal planet](https://reader033.vdocument.in/reader033/viewer/2022052623/559b2d4c1a28ab767b8b45c2/html5/thumbnails/2.jpg)
VITAL FUNCTIONS• There are vital functions that chracterise all living
things.
• NUTRITION
• INTERACTION
• REPRODUCTION
![Page 3: Animal planet](https://reader033.vdocument.in/reader033/viewer/2022052623/559b2d4c1a28ab767b8b45c2/html5/thumbnails/3.jpg)
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
![Page 7: Animal planet](https://reader033.vdocument.in/reader033/viewer/2022052623/559b2d4c1a28ab767b8b45c2/html5/thumbnails/7.jpg)
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)
![Page 8: Animal planet](https://reader033.vdocument.in/reader033/viewer/2022052623/559b2d4c1a28ab767b8b45c2/html5/thumbnails/8.jpg)
BODY PARTS OF VERTEBRATES
• Commonly the bodies of vertebates can be split
into:
• HEAD
• BODY
• LIMBS
![Page 9: Animal planet](https://reader033.vdocument.in/reader033/viewer/2022052623/559b2d4c1a28ab767b8b45c2/html5/thumbnails/9.jpg)
INVERTEBRATES
![Page 10: Animal planet](https://reader033.vdocument.in/reader033/viewer/2022052623/559b2d4c1a28ab767b8b45c2/html5/thumbnails/10.jpg)
Some animals don’t haveskeletons. They are INVERTEBRATES.
![Page 11: Animal planet](https://reader033.vdocument.in/reader033/viewer/2022052623/559b2d4c1a28ab767b8b45c2/html5/thumbnails/11.jpg)
INVERTEBRATES
• All invertebrates have one thing in common: they
are OVIPAROUS
• They aren´t VIVIPAROUS
![Page 12: Animal planet](https://reader033.vdocument.in/reader033/viewer/2022052623/559b2d4c1a28ab767b8b45c2/html5/thumbnails/12.jpg)

![Page 13: Animal planet](https://reader033.vdocument.in/reader033/viewer/2022052623/559b2d4c1a28ab767b8b45c2/html5/thumbnails/13.jpg)
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)
![Page 14: Animal planet](https://reader033.vdocument.in/reader033/viewer/2022052623/559b2d4c1a28ab767b8b45c2/html5/thumbnails/14.jpg)
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.
![Page 15: Animal planet](https://reader033.vdocument.in/reader033/viewer/2022052623/559b2d4c1a28ab767b8b45c2/html5/thumbnails/15.jpg)

ARACHNIDS• Their body is divided into two parts: Cephalothrax
and abdomen.
• Arachnids don´t have antennae or wings.
![Page 17: Animal planet](https://reader033.vdocument.in/reader033/viewer/2022052623/559b2d4c1a28ab767b8b45c2/html5/thumbnails/17.jpg)
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
![Page 19: Animal planet](https://reader033.vdocument.in/reader033/viewer/2022052623/559b2d4c1a28ab767b8b45c2/html5/thumbnails/19.jpg)

• They have poisonous tentacles that they use to hunt
other animals.
![Page 20: Animal planet](https://reader033.vdocument.in/reader033/viewer/2022052623/559b2d4c1a28ab767b8b45c2/html5/thumbnails/20.jpg)
ECHINODERMS• Starfish and sea urchins are echinoderms.

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.
![Page 22: Animal planet](https://reader033.vdocument.in/reader033/viewer/2022052623/559b2d4c1a28ab767b8b45c2/html5/thumbnails/22.jpg)
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
![Page 23: Animal planet](https://reader033.vdocument.in/reader033/viewer/2022052623/559b2d4c1a28ab767b8b45c2/html5/thumbnails/23.jpg)
REVIEW • All living things have three vital functions in order to
grow and live. These are: nutrition, interaction and
reproduction.
![Page 24: Animal planet](https://reader033.vdocument.in/reader033/viewer/2022052623/559b2d4c1a28ab767b8b45c2/html5/thumbnails/24.jpg)
REVIEW• Animals eat food to get energy. Carnivores only eat
meat and hervivores only eat plants. Omnivores eat
both meat and plants
![Page 25: Animal planet](https://reader033.vdocument.in/reader033/viewer/2022052623/559b2d4c1a28ab767b8b45c2/html5/thumbnails/25.jpg)

lay eggs.
![Page 26: Animal planet](https://reader033.vdocument.in/reader033/viewer/2022052623/559b2d4c1a28ab767b8b45c2/html5/thumbnails/26.jpg)
REVIEW• Animals with bones are called vertebrates and
animals without bones are called invertebrates.
Some animals have an external skeleton known as
a shell.
![Page 27: Animal planet](https://reader033.vdocument.in/reader033/viewer/2022052623/559b2d4c1a28ab767b8b45c2/html5/thumbnails/27.jpg)
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.
![Page 28: Animal planet](https://reader033.vdocument.in/reader033/viewer/2022052623/559b2d4c1a28ab767b8b45c2/html5/thumbnails/28.jpg)
REVIEW• There are other groups of invertebrates that live in
water. They are jellyfish, molluscs, sponges,
echinoderms and worms.
