Ecosystems: How Everything Connects Together
Exploring nature's amazing connections Year 4 Science Understanding how living things depend on each other

What Do You Think?
Look around our classroom What living and non-living things can you see? How might they be connected?

What is an Ecosystem?
A community of living things All the non-living things around them How they all work together Like a big natural family!

Parts of an Ecosystem

Producers: The Food Makers
Plants are producers They make their own food using sunlight They don't need to eat other living things All life depends on them!

Primary Consumers: The Plant Eaters
Animals that only eat plants They are herbivores Examples: rabbits, deer, caterpillars They get energy from plants

Secondary Consumers: The Meat Eaters
Animals that eat other animals They are carnivores Examples: foxes, birds of prey, spiders They get energy from eating other animals

What Happens When We Change Things?
If we remove all the foxes from a woodland... What do you think would happen to the rabbits? What about the plants they eat? How might this affect the whole ecosystem?
