How do rock platforms increase survival rates of juveniles?
Their crevices and hiding places offer refuge from predators and turbulence, boosting survival.
What food sources on rock platforms support juveniles?
Algae, barnacles and other microorganisms that form the base of the food chain.
What skills do juveniles develop on uneven rocky terrain?
Strong swimming and navigational skills important for later survival.
How do rock platforms contribute to ecosystem connectivity?
They act as stepping stones for movements between estuaries, seagrass beds and open waters.
How do rock platforms help maintain population resilience?
By facilitating movement that supports genetic diversity and population resilience.
What organisms form the base of the food web on rock platforms?
Sessile organisms such as algae, barnacles and mussels attached to the rocks.
Which herbivores graze on these base organisms?
Limpets and sea urchins.
How do small fish feed on rock platforms?
They forage among rocks for invertebrates.
How do larger predatory fish use rock platforms for feeding?

Name two predatory fish groups mentioned that hunt around rock platforms.
Wrasses and rockfish.
Why are rock platforms important feeding grounds for seabirds?
Accessible, diverse prey in crevices and tidal pools attract birds like gulls, cormorants and shorebirds.
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.
Why are nearby food resources on rock platforms critical for seal pups?
Mothers rely on them to nurse and sustain themselves, aiding pup survival.
As habitats, what do rock platforms fundamentally provide?
Places to live and shelter for many species, supporting biodiversity and ecological balance.
