Content descriptor use models, including food webs, to represent matter and energy flow in ecosystems and predict the impact of changing abiotic and biotic factors on populations

Elaborations

• • Elaboration analysing food webs to show feeding relationships between organisms in an ecosystem and the role of microorganisms
• • Elaboration modelling how energy flows into and out of an ecosystem via the pathways of food webs
• • Elaboration predicting the effects on local ecosystems when living things such pollinators or predators are removed from or die out in an area
• • Elaboration examining how events such as seasonal changes, destruction of habitat or introduction of a species impact abiotic and biotic factors and cause changes to populations
• • Elaboration investigating First Nations Australians’ responses to invasive species and their effect on food webs that many communities are a part of, and depend on, for produce and medicine
• • Elaboration considering how First Nations Australians’ fire management practices over tens of thousands of years have changed the distribution of flora and fauna in most regions of Australia
