1. Starter – What’s different about these food chains? What impact do you think this difference will have on the top consumer?

2. Why do we always eat Herbivores? Objective: to list where energy is lost in a food chain and use this information to explain why we rear herbivores for food Good You can list where energy is lost in a food chain Better You can describe the three different methods of farming Best You can explain why we rear herbivores for food

3. Energy Loss You can list where energy is lost in a food chain Use the sheet to help you label the cow What energy goes in? What is wasted and how?

8. Why is it better to eat herbivores? 1J of energy enters the human 10J of energy enter the cow 100J of energy enter the grass You can explain why we rear herbivores for food 0.1J of energy enters the big bird 1J of energy enters the small bird 10J of energy enter the caterpillar 100J of energy enter the plant

10. To Finish

11. Energy Loss

12. Battery Farming Chickens kept tightly packed in small cages to stop them moving 300 eggs produced a year Given antibiotics to prevent disease running through the entire barn Hens tightly packed to help keep them warm – no need for feathers

13. Barn Farming Lots of hens in one big room – slightly more space to move Approx. 280 eggs per year per chicken Heated barn to reduce need for feathers Given antibiotics to prevent disease running through the entire barn

14. Free Range Farming Lots of room to move about – open space and not too many chickens No heating so feathers needed to keep warm Approx 250 eggs per year per chicken No drugs give unless necessary – not much risk of all chickens being infected
