Hello, my name is Mrs. Mehrin and I'm really looking forward to learning all about creating food chains with you.

Let's begin.

Welcome to today's lesson from the unit, More about Food Chains.

Your learning outcome is I can carry out research and create food chains.

So here are your keywords for today's lesson.

Now, I am going to be referring to these keywords and their definitions throughout today's lesson.

However, if you find it helpful, you can pause the video here and you can jot these down.

Off you go.

Fantastic.

Well done.

Now your lesson is put into two parts today.

Let's begin with the first part, creating food chains.

Now, Andeep and Izzy would like to create their own food chains, and Andeep says, "We can use information about how living things depend on each other for food." And Izzy says, "We will create food chains to show what our favourite animals eat in order to survive." Now Andeep's favourite animal is a snake called an adder.

And here we have a picture of that snake.

Now, Andeep says, "I know that a food chain starts with a plant, so an adder will not be the producer in my food chain.

I need to think about what is food for an adder." Do you know? I'll give you five seconds to think about your answer.

Off you go.

Fantastic.

Well done.

Snakes including adders are carnivores.

Now carnivores are types of animal that only eat meat.

So some snakes eat warm blooded prey such as rodents, rabbits, or birds, while others eat insects, earthworms, slugs, amphibians, fish, or other reptiles.

So they've got really varied diet.

And Andeep eat says, "I know that adders eat mice, so I will include a mouse in my food chain." Now let's do a quick check-in of your learning before we continue.

And it says, what information can be used to create food chains? Is it A, how living things depend on each other for shelter? B, how living things depend on each other for food.

C, how living things depend on each other for warmth.

Again, I'll give you five seconds to think about your answer.

Off you go.

Fantastic.

Well done.

The answer is B, how living things depend on each other for food.

Now Andeep says, "I will begin to create my food chain.

I need to include arrows between each living thing.

Have I done this correctly?" What do you think? I'll give you five seconds to think about your answer.

Off you go.

Fantastic.

Well done.

So the arrows in a food chain represent 'is food for' and Andeep has turned the arrow around.

Is this correct now? Well, let's check.

He's saying that the adder is food for the mouse, so that's not correct.

So the second one is correct.

This is the correct way to show that the mouse is food for the adder.

And Andeep says now I need to think about what is food for a mouse.

I know that mice are omnivores.

So remember, omnivores are animals that eat plants and other animals.

Now, Andeep says they eat seeds, grains, and other plant materials, and also small animals such as insects.

So that's what makes a mouse an omnivore.

Now Andeep adds sunflower seeds to his food chain.

So we've got the sunflower seeds, our food for the mouse, and the mouse is food for the adder.

Andeep says, "I would like to add one more animal to my food chain.

I watched a television programme about how adders can be food for some other snakes such as the smooth snake." So now we've got sunflower seeds is food for a mouse, the mouse is food for the adder, and the adder is food for the smooth snake.

Now, who do you think is correct? Andeep says, "The arrows in a food chain represent 'depends on.

' And Izzy says, "The arrows in a food chain represent 'is food for.

' Now, what do you think? Who do you think is correct? I'll give you five seconds to think about your answer.

Off you go.

Fantastic.

Well done.

Izzy is correct, the arrows on a food chain represent 'is food for.

' Now here is your first task.

It says, arrange these living things and add arrows to create a different food chain to Andeep's which includes an adder.

So you're going to think about what comes first in a food chain, what eats that thing in the food chain, what is the first item in the food chain? What is that food for? And then you are going to continue this process until you have completed another food chain for Andeep, which includes his favourite animal, which is the adder.

So I'd like you to pause the video here and have a go at doing this activity.

Off you go.

Fantastic.

Well done.

So the grass is food for the grasshopper, the grasshopper is food for the frog, the frog is food for the adder, and the adder is food for the badger.

Did you get that correct? Now here is the second part of our learning say, which is researching food chains.

So here is the food chain that Andeep has created.

Do you remember this one? So this one was where you had the sunflower seeds, which is food for the mouse, the mouse is food for the adder, and the adder is food for the smooth snake.

Now food chains consist of a producer and consumers including predators and prey.

Can you identify the producer and the consumers, which are the predators and the prey? I'll give you five seconds to think about your answer.

Off you go.

Fantastic.

Well done.

So Andeep says, "I know that sunflower seeds are from a plant so they are the producer in my food chain." So remember, the producer produces its own food.

The mouse adder, and the smooth snake are consumers because they eat other animals or plants.

Now, Andeep asks Izzy to help identify predators and prey in his food chain.

Izzy says a predator is an animal that hunts kills and eats other animals.

The adder is the predator of the mouth, and the smooth snake is the predator of the adder.

And Andeep says, "Ah I see! So the animals that are eaten by other animals are prey.

These are the mouths and the adder in my food chain." Now let's have a look at these three statements.

Which statement is true? Is it A, food chains consist of producers, predators and prey? B, food chains consist of habitats and microbit habitats? or C, food chains consist of roots, stems and leaves? So think about what you've been learning about today to help you to answer this question.

So I'm going to give you five seconds to think about your answer.

Off you go.

Fantastic.

Well done.

The answer is A, food chains consist of producers, predators and prey.

So Izzy wants to create a food chain for her favourite animal, which is a dolphin.

And Izzy says, "I have never seen a real dolphin.

I don't know which animals are predators and prey of dolphins." Do you think you can help? Do you know? I'll give you five seconds to think about your answer.

Off you go.

Fantastic.

Well done.

So information that has been gathered by other people is called a what? A primary source of information, a secondary source of information or multiple source of information? I'll give you five seconds to think about your answer.

Off you go.

Fantastic.

Well done.

The answer is B, secondary source of information is information that has been gathered by other people.

Now, going back to Izzy's favourite animal, which is a dolphins, Izzy and Andeep look on the internet to research information our dolphins.

So they're looking at secondary sources of information.

And they search, which animals are the prey of dolphins? And the answer comes up with a variety of small fish, squid, krill, shrimps, jellyfish, and octopuses.

So this means that dolphins hunt and eat these animals.

Then they search which animals are predators of dolphins.

Orcas and large sharks, such as dusky, great white and tiger sharks are predators of dolphins.

This means that they hunt dolphins and eat them.

Now, Izzy uses the information from secondary sources to create a food chain that includes a dolphin.

So here we've got a krill, which is food for a dolphin, and the dolphin is food for the orca.

Now, what do you think is missing from Izzy's food chain? So I need to think really carefully about food chains that you have seen before.

What has Izzy missed out from her food chain? I'll give you five seconds to think about your answer.

Off you go.

Fabulous.

Well done.

So Izzy says, "I need to start my food chain with a producer, but I don't know what krill is and what plants they eat.

I will read a book as a secondary source of information to research this." What a fantastic idea.

Now, in her book about krill, it says, krill belonged to a group of animals that live in the ocean, including shrimp, crabs, and lobsters.

Krill are known to feed on microscopic marine animals and plants found near to the surface of the ocean.

Now Izzy completes her food chain.

So now she's got her marine plants, which is food for the krill.

The krill is food for the dolphin, and the dolphin is food for the orcas.

And Izzy says, "Secondary sources of information have helped me to research what food the animals in my food chain need to survive." So using secondary sources of information can help us to find out more by A, researching, B, observing or C, measuring.

Which one do you think using secondary source of information can help us to find out more by.

I'll give you five seconds to think about your answer.

Off you go.

Fantastic.

Well done.

The answer is A, researching.

So here is task B.

It says, use secondary sources of information to create a food chain for your favourite animal.

Remember to include a producer and consumers, including predators and prey.

So I'm going to give you some time now.

I'd like you to pause the video here and have a go at doing task B.

Off you go.

Fabulous.

Well done.

So I've gone for pandas, which are my favourite animal.

So the bamboo is food for the panda, and the panda is food for a snow leopard.

Now, is your favourite animal different to this? So now we are on to the summary of our learning today.

Information about how living things depend on each other for food can be used to create food chains.

The arrow inner food chain represents 'is food for.

' Food chains consist of a producer and consumers, including predators and prey.

Secondary sources of information help us to research what food different animals eat to survive.

Now you have worked so hard in today's lesson.

I'm so proud of you.

You have constructed some fantastic food chains and use secondary sources to help you.

Well done.
