The Jingeri Food web
By Tracy andSine Finnegan.

What makes up a food web?
A food web is made up of lots of food chains
They consist of Producers, Consumers and decomposers
They have large amounts of herbivores and carnivores
The producer: sun or energy is converted into living plants
The consumer: bird or koala, dingo or eagle
the decomposer: fungi and soil animals
Together all these are linked to create ecosystems

What parts of a food web make up
the Jingeri Ecosystem?
![Page 4: Understanding the ecosystem food chains at Jingeri](https://reader035.fdocuments.in/reader035/viewer/2022062709/558e58ca1a28ab546e8b4738/html5/thumbnails/4.jpg)
Primary producers
Energy from the sun
Energy stored in the plant and some escapes (heat)
Nutrients in the soil

Consumers
Herbivores Carnivores

Decomposers:Natures recyclers
minerals Manure/compost/dead things
Fungi:• Yeasts• Molds• Mushrooms
Soil animals:• worms• dung beetles• centipedes
Soils in which the primary producers grow

How does all that fit together???

What special ecosystems do we
have at Jingeri?

Glossy Black Cockatoo
Open Woodland/she-oak ecosystems
Allocasuarina = She-oak• Open grassy woodland• Mixed Eucalypts• Nests in large hollows in old trees• Glossy Blacks will only eat the cones
from the she-oaks• The cones are called “orts”• Under threat because of land clearing
of its food & habitat trees

Long Nosed Potoroo
Open Woodland Ecosystems• Open grassy eucalypt forests• With a diversity of native grass
species• Eats fungi, seeds and insects • Fungi is very important part of
their diet• Fungi essential to make healthy
soils• As a decomposer it is responsible
for Nutrient cycling into soils and plants
• Helps make the nutrients trapped inside dead plants and animals available for the plants and animals to use for energy.
• Under threat by predation from dogs, cats and foxes.
• Known to live in the same ecosystem as the Hastings River Mouse and the Eastern Bristle Bird.

KoalaEucalypt forest Ecosystems
• Eats only eucalyptus leaves from 19 out of 600 species of eucalypt trees.
• Relies on healthy ground cover between food and habitat trees to move safely on the ground.
• Threatened by habitat loss and predation from dogs and foxes.
• Suffers from a disease called Chlamydia which occurs in stressed animals.
• Koalas are becoming more and more threatened in SEQ because of humans

Everything in an ecosystem is connected to everything
else:They are “interconnected”

What have we learned?• Everything in a foodweb is connected
• Lots of different foodwebs make up an Ecosystem
• Healthy soils are vital to make sure energy and nutrients are available plants

Thank you for listening
What kinds of ecosystems or
foodwebs are there in your back yard?
