  • What organisms form the base of the food web on rock platforms?
    Sessile organisms such as algae, barnacles and mussels attached to the rocks.
  • What makes the intertidal zone on rock platforms unique?
    It is alternately exposed and submerged by tides, supporting organisms adapted to both conditions.
  • Why are nearby food resources on rock platforms critical for seal pups?
    Mothers rely on them to nurse and sustain themselves, aiding pup survival.
  • What advantage do stable rock surfaces give sessile organisms?
    They allow attachment and growth, creating dense communities and extra microhabitats.
  • What role do rock platforms play for juvenile marine organisms?
    They act as nurseries that provide essential conditions for early life stages of fish and crustaceans.
  • What skills do juveniles develop on uneven rocky terrain?
    Strong swimming and navigational skills important for later survival.
  • How do larger predatory fish use rock platforms for feeding?
    They feed on the smaller fish that gather there.
  • How do rock platforms help maintain population resilience?
    By facilitating movement that supports genetic diversity and population resilience.
  • How are rock platforms linked to Indigenous livelihoods?
    They provide rich food sources harvested through traditional practices passed down through generations.
  • Name two predatory fish groups mentioned that hunt around rock platforms.
    Wrasses and rockfish.
  • How is traditional ecological knowledge used alongside science in managing rock platforms?
    It is integrated with contemporary science to create a holistic, adaptive conservation approach.
  • What natural indicators guide the timing of harvesting?
    Tide patterns and celestial events.
  • How do organisms use rock platforms differently at high and low tide?
    They shelter at high tide and are exposed and foraging at low tide.
  • What principle underpins Indigenous harvesting on rock platforms?
    Sustainable use that respects ecological balance and seasonal cycles.
  • As habitats, what do rock platforms fundamentally provide?
    Places to live and shelter for many species, supporting biodiversity and ecological balance.
  • How do small fish feed on rock platforms?
    They forage among rocks for invertebrates.
  • How do rock platforms support fish during key life-cycle stages?
    They provide protected areas used for territorial behaviour, courtship and spawning.
  • Name three traditional techniques used for harvesting on rock platforms.
    Spearing, trapping and gathering.
  • What food sources on rock platforms support juveniles?
    Algae, barnacles and other microorganisms that form the base of the food chain.
  • How do rock platforms increase survival rates of juveniles?
    Their crevices and hiding places offer refuge from predators and turbulence, boosting survival.
  • Why are sheltered spaces and crevices significant on rock platforms?
    They offer refuge from predators, currents and waves, especially for juveniles and small invertebrates.
  • Which herbivores graze on these base organisms?
    Limpets and sea urchins.
  • What does custodianship of rock platforms involve?
    Careful harvesting and active participation in conserving these ecosystems.
  • What cultural markers might be found on rock platforms?
    Engravings, paintings or other markers.
  • Give three organisms that thrive in the intertidal zone of rock platforms.
    Crabs, snails and sea anemones.
  • How do rock platforms contribute to ecosystem connectivity?
    They act as stepping stones for movements between estuaries, seagrass beds and open waters.
  • Why are rock platforms important feeding grounds for seabirds?
    Accessible, diverse prey in crevices and tidal pools attract birds like gulls, cormorants and shorebirds.
  • Why are rock platforms culturally significant for Aboriginal and/or Torres Strait Islander Peoples?
    They are sacred places tied to stories, ceremonies and enduring connections to sea Country.
  • How do rock platforms support migratory bird biodiversity?
    By providing reliable feeding areas that support diverse bird populations.
  • How do seals and sea lions use rock platforms?
    They haul out to rest and give birth near reliable food resources.
