Homeostasis

How is an organism’s internal environment maintained in response to a changing external environment?

 

construct and interpret negative feedback loops that show homeostasis by using a range of sources, including but not limited to: (ACSBL101, ACSBL110, ACSBL111)

  • temperature (ACSBL098)

  • glucose

investigate the various mechanisms used by organisms to maintain their internal environment within tolerance limits, including:

  • trends and patterns in behavioural, structural and physiological adaptations in endotherms that assist in maintaining homeostasis (ACSBL099, ACSBL114)

  • internal coordination systems that allow homeostasis to be maintained, including hormones and neural pathways (ACSBL112, ACSBL113, ACSBL114)

  • mechanisms in plants that allow water balance to be maintained (ACSBL115)
