Food Chains
What can we eat?
• Before we decide what we will eat on our island we need to learn about feeding relationships
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)
Food Webs
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
Sun Sun Oak Tree Oak Tree Caterpillar Caterpillar Shrew Shrew Fox Fox

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.
