Unit 5.3 Impacts on ecosystems Strand Content Suggested teaching and learning strategies Pearson science New South Wales 7 resources Register Knowledge and Understanding LW5 Science and technology contribute to finding solutions to conserving and managing sustainable ecosystems Students: d predict how human activities can affect interactions in food chains and food webs, including examples from Australian land or marine ecosystems (ACSSU112) [CCT] e explain, using examples, how scientific evidence and/or technological developments contribute to developing solutions to manage the impact of natural events on Australian ecosystems [L] [CC] Sustainable ecosystems Define a sustainable ecosystem as one that can provide for the needs of organisms over a long period of time. Student Book 7, p. 198 Traditional use of fire Explain that fire is a natural part of the Australian environment and plants are adapted to survive fires. Explain traditional Aboriginal peoples’ use of fire for hunting. Student Book 7, p. 199 Fuel reduction burns Explain how controlled burning is used to limit the amount of fuel so that ‘cool fires’ will occur rather than ‘hot fires’. Student Book 7, pp. 199–200
