HOW DOES ENERGY FLOW THROUGH AN ECOSYSTEM?  An ecosystem consists of all the organisms living and in an area as well as the nonliving parts of that environment.

 the transfer of energy and matter in the form of food when one organism eats another organism.

Bell task: Spot the 12 differenceBell task: Spot the 12 difference 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  Oak Tree  Caterpillar  Shrew  Fox Card sort answers Did you get it right?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
