  1. Bell task: Spot the 12 difference Food Chains

  2. What can we eat? • Before we decide what we will eat on our island we need to learn about feeding relationships

  3. Food Webs Learning Objective :To recognise that food chains join to form food webs and to explore the effect of changing food chains on the whole ecosystem Success Criteria • Level 3 –Can order organisms into a food chain • Level 4- Can select a food chain from a food web • Level 5 – Can construct a food web from a selection of food chains • Level 6 – Can predict the effect a change in one food chain on the entire food web (ecosystem)

  4. Starter activity • Learning Objective: to be able to construct food chains • Using the cards provided and working in groups can you build an example of a food chain? • The cards you have are • Sun • Caterpillar • Fox • Oak Tree • Shrew

  5. Card sort answers • Did you get it right? • Remember we connect using arrows and • An arrow shows the direction of energy flow • Add these labels to your food chain: • producer, consumer, predator, prey herbivore, top predator Sun  Oak Tree Caterpillar ShrewFox

  6. Food Chains A different food chain. Use it to check your labels are correct. Producer Primary consumer Herbivore Prey Secondary Consumer Predator Prey Tertiary consumer Top Predator Carnivore     Wood mouse Barn Owl The sun Oak tree Bark Beetle

  7. Fox Owl Woodpecker Badger Squirrel Bat Hedgehog Mouse Dunnock Ant Centipede Stag Beetle Spider Caterpillar Aphid Moth Snail Fly Earthworm Woodlouse Trees and Woodland Plants

  8. Plenary • Now complete the food web given

  9. Fox Owl Woodpecker Badger Squirrel Bat Hedgehog Mouse Dunnock Ant Centipede Stag Beetle Spider Caterpillar Aphid Moth Snail Fly Earthworm Woodlouse Trees and Woodland Plants

  10. Food Webs Learning Objective :To recognise that food chains join to form food webs and to explore the effect of changing food chains on the whole ecosystem Success Criteria • Level 3 –Can order organisms into a food chain • Level 4- Can select a food chain from a food web • Level 5 – Can construct a food web from a selection of food chains • Level 6 – Can predict the effect a change in one food chain on the entire food web (ecosystem)

  11. Consumer Producer Carnivore Predator Bottom Predator Carnivore Prey Extra Task: Spot the mistakes Oak Tree Caterpillar FoxShrew Extension task: Correct Can you add any more organisms to the food chain to convert it into a food web. Explain what would happen if we started eating the shrews.
