Interactions between organisms, including the effects of human activities can be represented by food chains and food webs (ACSSU112)

Elaborations
  • using food chains to show feeding relationships in a habitat
  • constructing and interpreting food webs to show relationships between organisms in an environment
  • classifying organisms of an environment according to their position in a food chain
  • recognising the role of microorganisms within food chains and food webs
  • investigating the effect of human activity on local habitats, such as deforestation, agriculture or the introduction of new species
  • exploring how living things can cause changes to their environment and impact other living things, such as the effect of cane toads
  • researching specific examples of human activity, such as the use of fire by traditional Aboriginal people and the effects of palm oil production in Sumatra and Borneo
