The Great Sandy Desert
Transcript of The Great Sandy Desert
Example: Sturt's Desert Pea Producer: Autotroph Omnivore (Heterotroph): Organisms whose diet consists of both plants and animals in order to obtain sufficient energy.
Secondary Consumer: This consumer obtains its energy from the primary consumer.
Example: Bilby Omnivore A Carnivore (Heterotroph) is an organism that has a meat only diet. A carnivore is a type of Tertiary consumer which makes it last on the food chain. An example of a carnivore in The Great Sandy Desert is the King Brown Snake. King Brown Snakes are Tertiary consumers as they eat other reptiles, birds, mammals and lizards (secondary and primary consumers). Carnivore Decomposer (Heterotroph): An organism that gains it’s energy by breaking down wastes and the remains of dead organisms.
Example: Ants Location Herbivore Food Chain The Great Sandy Desert is located in the north-west of Western Australia. It stretches over approximately 360, 000 square kilometres and is the second largest desert in Australia. It covers the Pilbara and Kimberley Regions. A Herbivore is an organism that only eats plants. A Heterotroph is an organism that obtains food and energy by eating other organisms. A Herbivore is a type of Primary Consumer as it feeds on Producers (Autotroph) which get their energy from the sun. An example of a Primary Consumer in The Great Sandy Desert is a Desert Tree Cricket. Crickets eat things like spinifex and other plants so therefore classify themselves as herbivores. Food Web Detritivore A Detritivore is an organism that uses organic waste as a food source. An example of a Detritivore in the Great Sandy Desert is a Termite. Mutualistic Relationship Mutualistic Relationship: This type of relationship occurs when both organisms benefit from the other. Termites eat a lot of cellulose, but they can't digest it themselves. They have flagellates that live in their stomachs that digest it for them. The termites get improved nutrition, while the flagellates get a home and a steady supply of food. Decomposer (Heterotroph): An organism that gains its energy by breaking down wastes and the remains of dead organisms.
Example: Ants Decomposer Abiotic Factors Non-living features of an ecosystem.
• Geological Features (gorges, wetlands, grassland)
• Temperature Biotic Factors Biotic factors are all the living parts of an ecosystem. Some examples of Biotic factors in The Great Sandy Desert Ecosystem are:
• Desert bloodwood (Corymbia opaca)
• Paperbark tree (Melaleuca cajuputi)
• Bramble wattle (Acacia victoriae)
• Soft Spinifex (Trodia pungens R. Br.)
• Dwarf bearded dragon (Pagona minor)
• Scarlet-chested parrot (Neophema splendida)
• Fox (Pteropus scapulatus)
• Dingo (Canis lupus dingo)
• Red kangaroo (Macropus rufus) Introduced Species and Activity
• Cattle grazing
• Feral Foxes and Cats
• Human Settlement and Mining (iron ore) Problems facing the ecosystem Problems facing the ecosystem-disasters, environmental problems: • Sand Storms
• Mining (iron ore)
