As a little water vole feeds on bulrushes, a mother duck uses these plants as a safe place to hide her eggs. As newly-hatched tadpoles nibble on algae, dragonfly nymphs go hunting for tadpoles! And as frogs sit on lily pads to stay safe from big fish that want to eat them, small fish swim under the lily pads to hide from birds that are hunting at the pond. Step by step, readers will explore a pond habitat and discover how all the living things form an ecosystem and rely on each other for survival.
