Brushtail's claws changed as the amount of tree loss increased and the climbing claws it use to have had no need for it anymore and changing into digging claws for shelter. TEETH
The eyes of the brushtail adapted because it was forced to hunt during the day due to the amount of predators attacking though the day. The pupils had to shrink so that the sunlight wouldn't blind the possum Define the Words... Adaptation is a change in an organism that makes them better suited to survive and reproduce in a particular environment. Producers are organisms that make their own food A consumer is any animal that depends on plants and receives their energy by consuming other organisms. Herbivores are animals that feed on grass and other plants Carnivores are animals that feed on the flesh of other animals. Food Wed is a simple diagram that shows which organisms eat what and show links to represent energy flow. Food Web Adaptation Producers Consumers Herbivores Carnivores Common Brushtail Possum SELECT AN ANIMAL THAT LIVES WITHIN YOUR LOCAL AREA AND COMPLETE THE INFORMATION NAME? common name-
Trichosurus vulpecula APPEARANCE? Hence the name the common brushtail has a brushy tail and they’re only the size of an average cat. The male brushtail possums are generally larger than the females. Their feet have sharp claws and have a strong grasp The brushtail possum ranges in fur colour from grey, brown, black, red or cream. BEHAVIOUR? The Brushtail Possum is nocturnal and during the day they retreat to any dark area even inside roofs of houses. They are not usually aggressive towards each other but they stick their ears up and stare at each other when they come into contact with another brushtail. Brushtail Possums start breeding from one and baby possums are born in Autumn. HABITAT? Common Brushtail possum’s main habitats include areas of suitable trees to supply them with a source of food and shelter. Being very adaptable animals some have become urbanised and have made a home in made-made structures such as roofs of houses. Brushtail possum in a tree Brushtail possum under a roof Brushtail possum range in Australia FOOD? Generally the common Brushtail possum diet consists of leaves, blossoms, seeds and fruits. Sometimes it will eat insects depending on the area and the other food available. THREATS? Main predators of the common brushtail include foxes, cats and dogs, goannas and humans. More threats to the Common Brushtail Possum include loss of habitat.

BODY SIZE- the brushtail's body size lets the possum to move quickly and hardly be seen from its predator MY ANIMAL IS FORCED TO SURVIVE DUE TO CLIMATE CHANGE BY ADAPTING ITSELF. DESCRIBE 5 CHANGES TO MY ANIMAL SO IT CAN SURVIVE AND DRAW THE RESULT. LEGS Appearance CLAWS EYES Since the scarcity plants the brushtail had to evolve into a carnivore. The main need of being a carnivore is teeth and the brushtail adapted by growing bigger sharper teeth The increase on predator attacts the brush tail had to evolve to protect itself. Doing this the brushtail had to create a hard exterior and also blend in with it's new environment Before the Brushtail's evolutionary change it had little hind legs but with the tree loss it had no choice but to go on land and build up leg muscle to run from predators. TREE
HUGGER SELECT A TREE THAT GROWS WITHIN YOUR LOCAL AREA AND COMPLETE THE INFORMATION CONSUMERS OTHER THREATS NAME? COMMON NAME-
Acacia Longifolia APPEARANCE The Sydney Golden Wattle is a small tree but often grow as a large wide bushy shrub with fragrant, fluffy, golden flowers and long, thin dark green leaves. It also has smooth, dark brown to grey bark and the seed pods are brown, flat, and hairy. The green and gold colours used by Australian international sporting teams were inspired by the colours of the wattle. The Sydney Golden Wattle grows in Queensland New South Wales Victoria and South Australia. Flowering occurs from early winter through early spring SYDNEY GOLDEN WATTLE The consumers of the Sydney Golden Wattle include Australian Aboriginals who use the plant for medicine and food. It can be used for timber, fuel wood, food, herbal medicine, and a shelter tree. Insects such as bees suck the wattles nectar and use it for their honey. The Sydney Golden Wattle is not listed as being a threatened species and is considered very popular. birds bees ants spiders australian aborigines possums (fruit, leaves, seeds, sap) insects Describe 5 adaptations of your plant and explain how each helps the plant to survive in its environment The wattle adapted to the dry weather by dropping their leaves completely to save energy 1 2 The stalk contains far fewer pores than the leaf. Fewer pores means less water is lost through evaporation. The wattle leaves turn silver/grey to survive the extreme heat in Australia. 3 4 They have a short lived life and grow fast so they can respond to the changed environment. 5 During the harsh Australian fires the seeds of the Sydney Wattle open and reproduce better. Your plant is forced to “evolve” due to climate change. Describe 5 changes that would have to occur in your plant so that it can survive. The BRUSHTAIL possum is a native animal to Australia and it ranges from most of the eastern and northern parts of Australia and some part of the Western Australia. 1 2 3 4 5 LEAVES- The leaves changed as they adapted to the climate. They became smaller and thinner with a sharp point at the end to save water from evaporation. BARK- As the weather became hotter the bark on the tree became harder for the heat to be rebounded against the trunk so that the tree would no over heat and die. SEEDS- The seeds evolved by producing more so that there was more of a chance that they would grow and survive in the new climate and environment. ROOTS- The roots are the most important part of a plant. Having longer and stronger roots means that the Sydney Golden Wattle can absorb and hold more water and nutrients from the ground. PROTECTION- Stored water in a dry environment requires protection from thirsty animals. The spikes on the tree allow the tree for protection so that the animals don't drink all of the trees water.
