In this activity, students construct a food web using string and pictures. Their web will show the network of species in the ecosystem that is supported by honeydew produced by scale insects.

By the end of this activity, students should be able to:

  • describe relationships between particular organisms within the New Zealand bush ecosystem
  • build their own food web to show the interdependence of organisms in an ecosystem.
