Constructing food webs
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.
Honeydew
Honeydew is produced by a type of scale insect. Researcher Rosa Henderson, of Landcare Research NZ Ltd, talks about this resource and its role as a food source for birds, fungi and 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.
