As aphids suck nectar from the stems of plants, a ladybird leaves its winter hiding place to start munching on aphids. As worms wriggle through the soil helping to bring nutrients and rainwater to the roots of the garden’s trees, a robin hunts for worms to feed to its chicks.

Step by step, readers will explore a garden habitat and discover how all the living things form an ecosystem and rely on each other for survival.
