WORKSHEET NOTES: FOOD CHAINS (LOWER KS2):
Food chains begin with a “producer”, almost always a green plant. Animals are primary or secondary consumers. The food chain order should be: sun - nettle - insect - spider - blue tit (you can use the illustration, left, to demonstrate how this works after they’ve finished the worksheet above).
Rats will eat all of these, including baby blue tits and dead adults. They also eat plants, nuts, seeds, snails, shellfish, eggs, mice, waste food and (if all else fails) weaker rats. It’s this staggering range of foods that helps make rats so successful. They eat about 30g of food and drink 60ml of water a day, urinating profusely and leaving 40 droppings a day behind them. Some creatures will eat rats - birds of prey for instance.
Discussion points: If you were to make a list of animals in the food chain, what poll position would you give to the rat? What might eat a rat?
