What are the differences between Living things and Non-living things? DOLPHIN

NON-LIVING THINGS

LIVING THINGS

Living things are born. Living things grow . Living things die. Living things perform the three vital functions: NUTRITION RELATION REPRODUCTION

SEA STONES

Non-living things aren´t born. Non-living things don´t grow . Non-living things don´t die. Non-living things don´t perform the three vital functions.

How can we classify living thing? We can classify living things into five groups known as kingdoms. These five kingdoms are formed by plants, fungi, animals, algae and protist and bacteria.

How can we classify living things? We can classify living things into five kingdoms. These five kingdoms are formed by plants, fungi, animals, algae and protist and bacteria.

Plant kingdom

Plants use air, water and light to make their food. Plants don´t have sense organs. Plants cannot move from one place to another because they are attached to the ground by their roots.

What do plants use to make their own food? Plants use air, water and sunlight to make their own food. Why can´t plants move?

Plants can´t move because they are attached to the ground by their roots.

What are the parts of a plant? The parts of a plant are stems, leaves and roots.

Parts of a plant • Leaves make food for the plant. • The petiole connect the blade and the stem. • The blade is the flat part of the leaf.

STEM

The stem grow above the ground. The stem supports branches and leaves. The stem carries water and minerals. The stem transports nutrients to other part of the plant. The stem of a tree is called a TRUNK.

ROOTS The petiole

The blade

Roots grow underground. Roots keep the plant fixed in one place. Roots absorb water and minerals to make food.

The vital functions of a plants Plants perform three vital functions in order to grow and live.

Interaction

Nutrition:

• Plants can react to the environment. • Some plants move towards the sun.

Plants make their food .

Reproduction Photosynthesis: • Plants absorb sunlight, carbon dioxide, water and minerals. Plants release oxygen into air.

Respiration: Plants absorb oxygen. Plants release carbon dioxide into air.

• Plants reproduce by seeds. • Plants reproduce by a piece of the same plant.

What three vital functions do plants perform in order to grow and live?

Plants perform three vital functions in order to grow and live. These vital functions are nutrition, interaction and reproduction.

Plant classification

Flowering plants They reproduce through flower, fruits or seeds.

They don´t have flowers, fruits or seeds. They reproduce through spores. Mosses and ferns are non- flowerings plants.

Woody and herbaceous plants

Woody plants

Herbaceous plants

Woody plants have hard stem.

Woody plants are divided into: Trees bushes Birch wild rose

Herbaceous plants have thin and flexible stems.

Wheat

Daisies

Fungi get their food from other living things. They don´t have sense organs. They can´t move from one place to another.

Fungi

mould mushrooms Other fungi are microscopic . For exmaple yeast. They can´t be seen with the naked eye.

Where do fungi get their food from? Fungi get their food from other living things.

Animals

Find food

Animals get their food from other living things.

Find shelter

Most animals can move around in order to

Some animals give birth to their young. Reproduce.

Other animals lay eggs.

Why do most animals move around?

Most animals move around in order to find food, shelter and reproduce.

Animals carry out three vital functions in order to live and grow.

NUTRITION • Animals need energy that come from food. • Food contains nutrients. Through the process of nutrition animals transform nutrients into energy.

Omnivore animals

• Animals cannot make their own food. Herbivore animals get their food from plants. Carnivore animals get their food by eating other animals. Omnivore animals get their food from animals and plants .

Carnivore animals

Where do herbivores, carnivores and omnivores get their food from? Herbivores get their food from plants, carnivores get their food from other animals and omnivores get their food from animals and plants.

Reproduction

Relation Human beings and animals interact with the world around them. When animals are hungry, they hunt other animals.

Living things can make other living things. Lions get birth to lions cubs.

This process is known as reproduction. types of reproduction Oviparous viviparous

Animal classification. Animals can be verbebrate or invertebrate

• Vertebrate animals have backbone. • Vertebrate animals have an internal skeleton. • Vertebrete animals have a lot of bones. • Vertebrete animals can be oviparous and viviparous. • Nearly all vertebrate animals have limbs such as feet, wings and fins.

backbone

Invertebrate animals. • Invertebrate animals don´t have internal skeleton or bones. • All invertebrate animals are oviparous.

A snail is an invertebrate animal. A snail is an oviparous animal.

Algae are protist.

Algae Algae live in water. Algae don´t have roots or leaves.

Algae make their own food.

Protists Protozoa are microscopic protists that feed on other living things. Protozoa can live in different habitats. Ameboa and paramecium are examples of protozoa.

ameboa

Bateria Bacteria are microscopic organisms that can live in different habitats. Some bacteria make their own food. Other bacteria get their food from other beings.

Ecosystems A Habitat is the place where it is natural for an animal, plant or other organism to live within an ecosystem.

Different habitats have different conditions such as temperatura, light, air, water or type of soil. These conditions are known as an environment. All living things interact in an ecosystem

A population is made up of all of the Individuals that belong to the same species.

A community is made up of various populations that depend on one another in a particular habitat.

community

An ecosystem is made up of all the living things that inhabit a particular place.

Food chain A food chain shows the feeding relationship between the different organisms within an ecosystem. The lion eats the deer. The deer eats the plant. The plant needs water, air and sunlinght to grow .
