Great Victoria Desert
Transcript of Great Victoria Desert
What is Great Victoria Desert?
Victoria Desert is located in the western and southern side of Australia. This is a desert ecosystem and it is the largest in Australia. Its coordinates are 29.1522°S , and 129.2596°E . The area of the desert is 418.800 km2. The climate in summer is between 30 and 40°C and in winter it is 15 to 25°C. The desert has many landforms like sand dunes, grass land plains, gibber plains and salt lakes.
Interaction of biotic and abiotic
The People and the Desert
People who loves traveling should not come to this desert, because in 1953-1963 the British used to use it as a nuclear testing area in Maralinga. What they use to test were plutonium and people believe that the area is still contaminated. About 3,500 people are already living in a town call Coober Pedy for residents work in mines, tourism, or are army personal on space programs and defense systems.
How are we destroying the desert?
People in the world gets paid by the government to do jobs that can harm the environment like mining in the desert. They use giant machines like a "nodding donkey" that could destroy the wildlife there. They use it to dig in through the soil for oil, rocks containing precious metals and materials. The Super Pit was Australia's largest open-pit gold mine and people are digging in there to find gold. Not only does it affect the land but the oxygen because of the air pollution it is making.
Great Victoria Desert
Biotic and Abiotic
Biotic factors: There are many reptiles, mammals, birds and insects . For example, snakes, lizards, and rats. Plants are also living organism.
Abiotic factors: Some abiotic factors in this desert are the sand, sunlight, water, air, and temperature.
Producers: Grass, weeds, cactus, flowers and trees
Composers: Snakes, rabbits, hawks, kangaroo rat, foxes, ants, and lizards
Decomposers: Fungi, scavengers, and bacteria

The interactions in this desert is, the sun, water and oxygen helps the trees, flowers and weeds (producers) grow which can become food for other animals. Then herbivores like rabbits, and rats (primary consumers) who eat the plants later gets eaten by carnivores like dingoes and owls (secondary consumers) to gain their energy and nutrients. Once these animals or plants dies decomposers like fungi, bacteria and scavengers turns them into nutrients for the soil. This cycle then repeats over again. A problem is sometimes the sun dries up the water there because they get little rain fall and could affect the plants and animals there.
Ways to protect it
How does mining and pollution affect the desert?
First, those machines called "nodding donkey" are destroying the soil which all plants need to produce food for other animals. If the plants are dying there wouldn't be food for the herbivores and later the carnivores because the those animals would die and there is nothing left for them. Food is not the only thing, the animals that live there, their homes are being taken away and being destroyed. For example, jack rabbits live underground and we are digging materials down there. This mining and polluting could really affect the entire ecosystem; their food and habitats.
Some ways we can all save this desert is by going there with safety equipments and plant new trees, food and helping repair the animals' habitat. By not allowing people and workers come here to mine and look for oil and gems, it can decrease the pollution here. Also the land won't be destroy by those machines and the animal population would increase more than before. Also, Clean Up Australia is an organization dedicated to educating people and to help clean up the environment. The more volunteers come and help the better and quicker the desert will continue living.
Carbon and Matter Cycle
When sunlight shines down on the trees and weeds, it collects the sun's energy and then releases oxygen into the air. This process is called photosynthesis. For this process to work the grass, cactus and trees will need sunlight, water, soil and carbon dioxide. Carbon dioxide comes from us breathing in the air the plants make and then releasing the carbon dioxide into the air for plants. Also when a living thing dies they become food for the plants so the carbon cycle would continue. The sun, soil and air helps plants grow which also feeds on animals. Once the animals die they later become food for the plants and the mater cycle keeps going.
Some natural disasters that have happen are mostly droughts, extreme heat, fire and sand storms. These natural disasters have destroyed many of the animals habitat and resources also vegetation for others. Although they don't occur a lot any more compare to the past.
Human and Animal Adaptations
Animals like snakes, lizards, birds, and dingoes could adapt here because can they survive in extreme heat. The human adaptions were the aboriginal people. They survived by damming on claypans and finding water in the roots of trees like black oaks.
