Transcript of McKayla's Australian Savanna Biome

By: McKayla Campagna
and Ryan Busche Australian Savanna Wildfires, water, soil, and sunlight
Wildfires contribute to developing habitat heterogeneity. It rains 20 to 50 inches every six month. soil is infertile and dry and is made up of dirt, clay, and sand. and sunlight is need for the plants to develop and it is not in low supply. Abiotic factors Emu, koala bear, dingo,
Jarrah, Kangaroo Paw, and Cycas armstrongii.
Emus are omnivores. koala bears are a mammal that survives on eucalyptus leaves. The dingo is a carnivore that hunts emu and other prey. Jarrah is the most common species of Eucalyptus tree. The kangaroo paw is a perch for the birds and can give nectar to the organisms. The Cycas armstrongii grows pendent fruit for other organisms to eat and survive on. Biotic Factors Food web Tertiary Consumers: Dingo Secondary Consumers: Emu Producers:Waffle Tree, Gum Tree, Grasses, Jarrah, Cycas armstrongii, and Kangaroo Paw Primary Consumers:Kangaroo, Wambat, Crickets, Termites, Blue- faced, Honeyeater, McKayla Campagna & Ryan Busche Australian Savanna Predator-prey: The dingo hunts the emu for food and help keep up the dingo population and keep the emu population under control.

Competition: the blue-faced honey eater and the termite both eat the plant called gum tree but both have a good abundance of other food to serve as a substitute.

Commensalism: The birds follow the wombat while its grazing and eats any insects that fly out of the grass but the wombat gets nothing and the birds get food Relationships within the biome
The koala bear used to be endangered, but since a law passed, hunters are forbidden to hunt koala bears for their fur. Hundreds of koala bears die because they have life threatening diseases.
There are less than 50,000 koalas left in the wild.
The majority of the reason as to why the koalas are becoming extinct is that, many hunters are killing them for their fur, and they can carry many diseases.

When one of the frequent fires in the savanna burns plants and produces rash rich in minerals which then leaves room for new plants to grow .

The biome would first change by new plants being introduced to the biome and then new animals which eat this plant could move in and it would switch up the food chain alot because the native species would not be used to the new species. The australiana savanna succession Carbon dioxide, greenhouse gases,- such as methane, and nitrous oxide are released into the atmosphere from fossil fuels. Stored carbon has been released through the clearing of vegetation. Increasing the amount of greenhouse gases in the atmosphere increases the ability to absorb heat. Carbon Dioxide effects the ecosystem in the Australian Savanna My prediction is that over a period of time the soil will become very rich from the frequent fires in the australian savanna and new plants that require rich soil will start to appear. the landscape will become green aside from a type of yellow. although this could only happen if the precipitation is also at a good point for the growth of plants.
