Here are some of the words that you'll become familiar with as we work on food chains:
Using the sun's energy, green plants make their own food = they PRODUCE food.
Animals which eat plants and other animals are consumers = they CONSUME food.
Some consumers only eat plants. These are herbivores.
Consumers that eat other animals are called carnivores.
Some consumers eat plants and other living things. Animals with a 'mixed' diet are omnivores.
OK, now we've got that sorted, let's put it into practise...
