Simple Food Chains
Open with the big idea that living things need food, and in science we can show who eats what in a simple chain.
What I am learning
I can identify plants as producers, arrange a simple food chain and explain how animals depend on plants and other animals for food.

What words pop into your mind when you hear food chain?
Use this as a prior-knowledge activation after the learning goal. Invite single words or short phrases such as plant, eat, animal, grass or arrows. Pick out any misconceptions to revisit later.
About this lesson
This KS1 science lesson explores Simple Food Chains. Pupils identify plants as producers, arrange simple food chains and explain how animals depend on plants and other animals for food. It is suitable for classroom teaching, independent practice or a clear recap of the topic.
This slide contains the user's required SEO text verbatim.
Food gives living things energy
All animals need food to live and grow
Food gives living things energy
Some animals eat plants
Some animals eat other animals
Keep language simple: food helps living things move, grow and stay alive.
Plants make their own food
Plants are called producers.
They use sunlight to make their own food, so a food chain usually starts with a plant.
At KS1, it is enough to say plants make their own food using sunlight. Avoid overloading with the full process of photosynthesis unless useful as teacher background.
Animals cannot make their own food
Animals must eat plants or other animals.
This means animals depend on other living things for food.
Emphasise the phrase 'depend on' because it is part of the required learning focus.
What is a food chain?
A food chain shows who eats what.
It starts with a producer and then shows the animals that get food from it.
Model reading a chain from left to right: the food is eaten by the next living thing.
Which living thing is a producer?
rabbit
grass
fox
owl
Checks the key idea from slides 3 to 6 that plants are producers because they make their own food.
Complete the food chain facts
A food chain shows who eats what. It starts with a producer. Animals cannot make their own food, so they depend on plants or other animals for food.
The blanks focus on the load-bearing vocabulary from the first teaching block.
A simple food chain
grass → rabbit → fox
Grass is the producer
The rabbit eats the grass
The fox eats the rabbit
Read the chain aloud several times. Pupils often reverse the arrow meaning, so stress that the arrow points to the eater.
How to read the arrows
The arrow means is eaten by.
grass → rabbit means the rabbit eats the grass.
rabbit → fox means the fox eats the rabbit.
This is a key misconception point. Keep returning to 'is eaten by' whenever arrows appear.
Plant-eating animals
Some animals eat plants.
Examples:
cow
rabbit
caterpillar
You do not need to introduce formal KS2 vocabulary unless helpful orally. The important idea is that these animals get food from plants.
Animal-eating animals
Some animals eat other animals.
Examples:
fox
owl
frog
Make clear that these animals still depend on plants too, because the animals they eat got their food from plants.
Animals still depend on plants
Even if an animal eats another animal, the chain still begins with a plant.
plant → plant-eating animal → animal-eating animal
This slide resolves the central idea: plants are the start of simple food chains.
In grass → rabbit, what does the arrow mean?
runs to
looks at
is eaten by
lives near
Targets the common misconception highlighted on slide 8. The arrow points to the eater.
Finish the simple chain
In a simple food chain, a plant comes first. Then a plant-eating animal gets food from it. Last, an animal-eating animal eats that animal.
This check-in matches the wording used on slide 11 and reinforces the order of a chain.
Food chain in a field
grass → mouse → owl
The grass is the producer
The mouse eats the grass
The owl eats the mouse
Use this as a fresh example so pupils do not think there is only one correct chain.
Food chain near a pond
pond plant → snail → duck
Living things in different places can make different food chains.
A pond plant can be any simple water plant; keep the example broad and age-appropriate.
Putting chains in order
To build a simple food chain:
find the producer first
add the animal that eats the plant
add the animal that eats that animal
This supports later arranging tasks without turning the slide into an activity.
If one part is missing
If there are no plants, plant-eating animals have no food.
If plant-eating animals have no food, animal-eating animals may have no food too.
Food chains show how living things are connected.
Keep this causal idea gentle and concrete for KS1: no plants means trouble for the whole chain.
Support and challenge
Support
Use the sentence stem: ___ is eaten by ___.
Start each chain by looking for the plant.
Challenge
Explain why a fox still depends on grass in the chain grass → rabbit → fox.
Although the lesson is content-only, this slide preserves the requested differentiation in a simple, student-facing way.
Which chain is in the right order?
owl → mouse → grass
grass → owl → mouse
mouse → grass → owl
grass → mouse → owl
Practical application of arranging a simple food chain using the field example.
Why does a fox still depend on grass?
Expected answer elements: a fox depends on grass because the rabbit eats the grass and the fox eats the rabbit. Encourage pupils to use the stem '_ is eaten by _'.
Complete the missing part idea
If there are no plants, plant-eating animals have no food. Then animal-eating animals may have no food too. This shows a food chain is connected.
Links directly to slide 15 and checks understanding that all parts of the chain are connected.
What is one thing you learned today?
Reflection only. Invite pupils to name one clear idea, example or rule from the lesson, such as plants are producers, arrows mean is eaten by, or a chain example they remember.
What helped you understand food chains best?
Reflection only. Encourage brief answers about supports such as the arrows, examples, sentence stem, or putting chains in order.
