Game: Food Web
Words you need to know
A food chain shows how each living thing gets energy through its food. Some animals eat plants and some
animals eat other animals. In a food chain, each link in the chain (or food source) becomes food for the next link
in the chain. The interconnecting food chains in a particular ecosystem are known as a food web.
Biodiversity (biological diversity) refers to the variety of all living things, including plants, animals, micro-organisms
found in an ecosystem and their inter-relationships.
Aim
To create a Tasmanian food web using the information on the animal picture and food cards provided.
To play
1. To begin, choose one animal picture card from the pack, and attach it or write the name of that animal in
the middle of a large piece of paper (or white board).
2. Find the food card related to that animal and read what it eats.
3. Write the name (or place the picture) of what it eats under the first card.
4. Draw an arrow from the food to the animal that eats it.
5. Choose another animal and do the same thing with the cards.
6. When you have made several food chains, look for and draw in any other links to create a food web.
Discovery questions
• What would happen if certain animals die out or their numbers decline?
• Describe an impact that humans might have on the food web in the area where you live?
• Name some threats to Tasmanian biodiversity.
• Fox sightings in Tasmania are increasing. If the fox population becomes established and increases even more
what implications (both short term and long term) will that have on the Tasmanian food web?
• What actions could be taken in your area to help to protect the biodiversity and reduce human impacts?
Further work
• Research the meaning of the terms producer, herbivore, carnivore and top order predator.
• Define threatened species and give some Tasmanian examples. You may like to use the web.
• Research the impact the European red fox has had on wildlife and agricultural practices on
mainland Australia. Depar tment of Primar y Industries, Parks, Water and Environment

European red fox (introduced)
Food: typically eats everything under 5 kg including
insects, lizards, frogs, mammals and some birds.
The Tasmanian pademelon and bettong are now
extinct on the mainland due to the fox. 78% of
Tasmania’s vertebrate species are at risk including
eastern barred bandicoot, eastern quoll and
long‑tailed mice.
25
black field cricket
Teleogryllus commodus
Food: grasses
The black field cricket is nocturnal and feeds at night.
To find a mate, it calls out at night by rubbing its wings
together. It lives in tunnels in pasture and grassland as
well as under rocks.

The Tasmanian devil is the largest marsupial carnivore.
It is nocturnal so it feeds during the night. It lives in
forest, woodland and agricultural areas.
The native hen is a flightless bird found only in
Tasmania. It feeds during the day and lives in grassy
paddocks near swamps, lakes or rivers. Females lay
4-9 eggs in a nest made of grass or tussock.
19
21
spotted-tailed quoll
common wombat
Dasyurus maculatus
Food: small birds, mammals, invertebrates and reptiles and
carrion (dead animals).
The spotted-tailed quoll is mainly nocturnal so it feeds
during the night. It is common in wet forest, coastal
heathland and agricultural areas.
17
Vombatus ursinus
Food: native grasses, herbs and shrubs.
The common wombat is mostly nocturnal so it feeds
during the night. Its habitat is widespread from coastal
to alpine areas.
22
brown goshawk
scrubtit
Accipiter fasciatus
Acanthornis magnus
Food: small mammals, reptiles and birds.
Food: insects.
The brown goshawk feeds during the day and flies
around forests, woodlands, farmland with trees and
urban parks. It spends most of its time in the forest
where it hunts by stealth.
The scrubtit feeds during the day and lives in the
dense undergrowth of wet forests, fern-gullies and
rainforests. It is secretive and hops up the trunks of
trees in search of food. Nests are often placed low
in shrubbery. It is endemic, that means only found
in Tasmania.
2
14
echidna
Tasmanian pademelon
Tachyglossus aculeatus
Food: ants, termites and other small invertebrates.
Food: grasses, herbs and shrubs.
The echidna lays eggs and feeds its young with milk.
It feeds during the day but can be active in the night.
It lives throughout Tasmania but is most common in
drier areas.
The pademelon is nocturnal so it feeds during the
night. It is widespread throughout Tasmania but is
most common in the dense undergrowth of forests
near cleared land.

Thylogale billardierii
#
metallic skink
ptunarra brown butterfly
Niveoscincus metallicus
Oreixenica ptunarra
Food: insects and other small invertebrates.
Food: nectar
The metallic skink feeds during warmer days
because it needs heat to enable it to move. It is the
most widespread reptile in Tasmania and is found
everywhere from coastal to alpine areas.
The ptunarra brown butterfly feeds during the day
in the warmer months. It is rare and lives in the
grasslands and grassy woodlands of the Midlands,
Northwest and Central Plateau.

13
flower spider
earthworm
Diaea rosae
(Oligochaeta)
Food: insects.
Food: decaying plant and animal matter.
The flower spider hides inside flowers and ambushes
small flies and other insects that come to feed on
the flower’s nectar and pollen. It lives in foliage and
flowers and feeds during the day.
The earthworm eats as it is tunnelling through the
soil, thus helping to keep the soil healthy. It lives all
over the world including in Tasmania’s soil.
