In this activity, students build a food web that represents the New Zealand bush ecosystem. Students use images of organisms within the ecosystem to explore the relationships between them.

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

  • understand the difference between a food chain and a food web
  • describe some of the relationships between organisms within the New Zealand bush ecosystem
  • explain why birds have an important role in the New Zealand bush ecosystem
  • explain possible outcomes of an imbalance of diversity within our ecosystems.
