Read the field notes

At a small nature display in a train station, Zoe and Tane spot an earthworm in a clear soil-viewing box. Their notes say: An earthworm has a long, soft body made of many rings called segments. It has no legs. Tiny bristles and strong muscles help it move through soil. Its skin must stay damp so it can breathe. Earthworms eat dead leaves and other rotting plant material. As they make tunnels, air and water can move through the soil. Their waste adds nutrients that help plants grow. Earthworms hide in cool, damp places and avoid dry, hot conditions.
