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

1 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

2 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.

3 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.

2 ANIMAL CLASSIFICATION 1 VERTEBRATES 2 INVERTEBRATES

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) feet wings fins Nearly all vertebrates have limbs: - Feet - Wings - Fins

VERTEBRATES classification birds mammals wings feet fish reptiles fins anphibians

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

INVERTEBRATES 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

INVERTEBRATES classification arthropods echinoderms molluscs jellyfish worms sponges

butterfly 3 Arthropods 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. beetle ARTHROPODS INSECTS 6 legs ARACHNIDS 8 legs ant CRUSTACEANS 10 legs ladybird

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

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

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

4 MORE INVERTEBRATES pores - 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. JELLYFISH Jellyfish have poisonous tentacles that they use to hunt animals and to defend themselves. tentacles

MORE INVERTEBRATES 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

MORE INVERTEBRATES MUSSEL MOLLUSCS valves shell SQUID SNAIL - 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

QUESTIONS

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

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.

Complete the table: ARTHROPODS BODY LEGS Insects Two parts 10 legs EXAMPLES

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

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

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 ……………
