What does the worm eat - pupils resources

The correct answers can be found in the teachers resources section

Clues for pupils to look out for:

Carnivores / Omnivores:

Worms which eat meat are likely to be active, in order that they can catch prey items. Therefore they are likely to have well-developed locomotive structures in order to crawl or swim. They are also likely to have structures for sensing prey, such as eyes and antennae. They may also have large mouths and/or jaws to capture prey (these may be hidden however).


Animals which get their nutrients from ingesting mud or sand are likely to be less active. Therefore they may live in a tube, and their locomotive structures may be less well-developed. They may or may not have eyes or antennae. They may have gills, which can be seen due to their red colour.
