Transcript of Great sandy desert

Food web
Food Pyramid
Food Chain
Australian feral camels were introduced during the 19th century as a form of transport. As these big animals flourished other smaller animals ran out of food do to the camels eating habits.
THE GREAT SANDY DESERT
Human impact
One of the most famous human impacts in Australia is poaching of red kangaroos. This has endangered red kangaroos, upsetting the ecosystem.
Carnivore
omnivore
Carnivore
Herbivore
producer
Biot:
feral camels, dingos, goannas, Bilbies, Mulgara, Marsupial mole,
Rufous hare-wallaby, Thorny Devils,
Bearded Dragons, and the Red kangaroo.
Soft Spinifex, Bloodwoods, Feather-top Spinifex,
small woody and herbaceous plants

Abiot:
Sand, Rocks, mountains, sand, high daytime temperatures and overnight temperatures along with far below average humidity levels.
Numbers of clear days are above average and wind speed and rainfall is below average. Numbers of cloudy days are average, more sand, hot sun.

Structural adaptation: A physical feature of an organism's body having a specific function that contributes to it survival.
Physiological adaptation: A physical or chemical event that occurs within the body of an organism that enables survival
Behavioral adaption: Refers to what an organism does to survive in the unique conditions of its environment.
The Perentie, which is a two meter long lizard that lives in The Great Sandy Desert uses underground burrows to shelter in.
For the Red Kangaroo hopping is a fast and very energy efficient way to travel around and find food in this very hot and scarcely vegetated desert.

Commensalism: a class of relationship between two organisms where one organism benefits without affecting the other.
Mutualism: a relation of two organisms of different species in which each individual benefits.
Parasitism: a relation between organisms in which one species benefits and another is harmed
Competition: is an interaction between organisms in wich they compete for the same resource such as food.
Predation: form of symbiotic relationship between two organisms of unlike species in which one of them acts as predator that feeds on the other organism that serves as the prey.
decomposer
Bilby and Perentie compete for shelter
The Thorny Devil eats ants
Mycorrihiza and desert plants, where the fungus colonizes the host plant's roots
Desert mistletoe and desert ironwood
Lichen growing on tree bark
In this predator - prey relation ship the dingoes prey on the hopper mouse. if there's a high mouse population the dingoes feed well and repopulate faster. Then as the dingo population increases more mice are being eaten and there population drops until it can't feed the dingo population. Thus the dingo population drops. and with less predators the mice can repopulate and the cycle continues
Bioaccumulation is the gradual build-up of synthetic and organic chemicals in living organisms.

It’s when a chemical gets introduced in an ecosystem and small animals consume it. As other animals eat the small animals with the chemical, the chemical builds up and causes harmful things like mutation or death.

for an example in Australia say that T.D.T. was introduced to prevent bugs from eating the plants. The bugs consume small amounts of T.D.T. Then mice eat the bugs gaining a larger amounts of T.D.T. Dingoes would eat the mice, consuming large amounts of T.D.T. thus causing death of the dingoes
Adaptive radiation: the development of a numbber of new species from a common ancestor; the new species are adapted to inhabit different niches

natural selection: the process in wich, over time, the best-adapted member of a species wil survive and reproduce.

Niche: the special role an organism plays in an ecosystem, including the way in which it contributes to and fits into its environment

native species: plants and animals that naturally inhabit an area

latitude: the distance measured in degrees north or south from the equator.

pioneer species: organisms such as lichens and other plants that are the first to survive and reproduce in an area.

species: a group of closely related organisms that can reproduce with another.

sustainability: the ability of an ecosystem to sustain ecological processes nd maintain biodiversity over time.

habitat: the place in which organisms live.

Climax community:A mature community, such as a boreal forest, tropical rainforest, grassland or desert that continues to change over time
A potential solution to this activity is to have bigger punishments for those who poach red kangaroos and a better patrol of red kangaroo herds
A population is a single species in some area.



A community is a group of populations in some area.



An ecosystem comprises all of the biotic (living) and abiotic factors in an area.
