Inside the World of the Koala

Question 1 · multiple choice

Which field camp would place a researcher closest to the natural home of a Koala?

tropical savanna soils and large ventilated mounds eucalypt woodland and forest in eastern Australia large lakes, deltas, lagoons, and sheltered coasts deep flowing rivers with sandbanks

Question 2 · multiple choice

Which food tray most closely copies what a Koala normally finds in nature?

tiny crustaceans sucked through a tube-shaped snout sugars from symbiotic algae plus filtered plankton selected eucalyptus leaves mainly jellyfish and other soft drifting animals

Question 3 · multiple choice

Which activity schedule best describes a Koala?

mostly feeds at night active by day mostly active at night rests for most of the day and feeds largely at night

Question 4 · multiple choice

A Koala must travel through its habitat. Which movement strategy does it actually use?

climbs with strong limbs, curved claws, and opposing digits walks slowly and sways like a twig in wind flies between feeding areas and hangs acrobatically while building climbs and leaps among leaves over water

Question 5 · multiple choice

A Koala succeeds in its habitat partly because of which adaptation?

nostril structures manage airflow while a third eyelid protects the eye a long digestive tract and microbes help process fibrous, toxic leaves dark skin absorbs heat and salt glands sneeze excess salt from the nose chromatophores, reflective cells, and skin muscles create rapid patterns and texture

Question 6 · multiple choice

A wildlife nursery prepares for a young Koala. Which developmental fact should guide the team?

eggs are laid in a tunnel excavated in a riverbank females guard mound nests and may carry hatchlings to water a joey grows in the pouch and later rides on its mother’s back adults build a foam nest where eggs and young receive protection

Question 7 · multiple choice

A group-behaviour study follows a Koala. Which result should the team expect?

may queue and swap shells when a better empty shell appears mostly solitary but may tolerate others in roomy shelters forms loose groups and may mix with grazing mammals mostly solitary, communicating over distance with scent and bellows

Question 8 · multiple choice

If Koala numbers fell sharply, which ecosystem service could be affected?

recycles nutrients from eucalyptus foliage and browses tree canopies preys on small crustaceans and provides food for larger fish filters water and builds calcium-carbonate habitat controls jellyfish and transports nutrients across ocean basins

Question 9 · multiple choice

Which defence strategy is actually used by a Koala?

soldiers block tunnels or use large jaws while workers seal damage climbs higher, grips bark, and uses claws when threatened uses size, bill jabs, and group vigilance retreats to deep water and uses teeth and tail if trapped
