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
