...on of mistletoe plants in that local ecosystem. The abundant plants would then heavily affect the gum tree populace in that area which in turn would affect organisms that eat the gum leaves. “Biology in Context” Q2) a) The Antechinus main habitat is in grasslands, open forests, woodlands, vine forests and rainforest and nest in tree hollows, logs, epiphytic ferns, creek banks or under grassy tussocks. Bate such as beetles, spiders, amphipods or cockroaches should be used. “http://www.parks.tas.gov.au/wildlife/mammals/dantech.html” b) 145 “Biology in Context” Q3) a) Questions/answers Question Fish # A 4 B 1 C 5 D 2 E 3 b) Q4) a) 1968 b) The time it takes for plantation to grow and the birth rate of the rodents after gestation would affect the population size during the favourable conditions. c) 4 months -Rattus villosissimus 1 month - Notomys alexisor d) Longer gestation period between 2 different species. With the higher birth rate of Rattus villosissimus the Spinifex is disadvantaged as most of the thriving plantation would be eaten already by the Rattus. Q3) The Hawkesbury Sandstone ecosystem (dry sclerophyll forest) was influence by the mostly the physical formation and surroundings. Caves and Heavy Bush, heat (temperature humid and arid) sandstone abundance (resulting in lack of water) have determined the characteristics of organisms including the Bush rat with traits including grey-brown fur to provide camouflage to hide from predators, becoming nocturnal to one save water and provide hiding places from predators and having a long naked tail to maintain balance allowing it to scale vertical terrain and maintain heat to avoid water loss. Tress such as the Scribbly Gum have also adapted with the ability to regenerate leaves after a fire. “A local ecosystem camp Kedron sheet” Q4) Mutualism: between rainbow lorikeet and the Banksia flower. The Lorikeet feeds off the nutricius nectar that the Banksia flowers holds. Whilst feeding the flower rubs pollen over the b...
