  Multicellular organisms rely on coordinated and interdependent internal systems to respond to changes to their environment

  Elaborations

  • describing how the requirements for life (oxygen, nutrients, water and removal of waste) are provided through the coordinated function of body systems, for example, the respiratory, circulatory, digestive, nervous and excretory systems
  • explaining (using models, flow diagrams or simulations) how body systems work together to maintain a functioning body
  • investigating the response of the body to changes as a result of the presence of micro-organisms

• VCSSU121

  Ecosystems consist of communities of interdependent organisms and abiotic components of the environment; matter and energy flow through these systems

  Elaborations

  • exploring interactions between organisms, for example, predator/prey, parasites, competitors, pollinators and disease vectors
  • using modelling to examine factors that affect population sizes, for example, seasonal changes, destruction of habitats, introduced species
  • investigating how ecosystems change as a result of environmental change, for example, bushfires, drought and flooding
