The Polar bear Challenge

Question 1 · multiple choice

Which landscape is most suitable for a wild Polar bear?

rocky shores and shallow seabeds Arctic sea ice, coasts, and nearby islands gardens, hedges, woodland edges, and tall vegetation open African savanna and grassland

Question 2 · multiple choice

Which description best matches the natural diet of a Polar bear?

rodents, rabbits, birds, and lizards crabs, clams, fish, and other marine animals mainly seals reached from sea ice milkweed as caterpillars and flower nectar as adults

Question 3 · multiple choice

A tracking tag records the daily rhythm of a Polar bear. Which pattern is the best match?

workers forage day and night depending on temperature and humidity feeds by day or night in suitable shallow water often hunts by day and rests during hottest hours can be active at any hour depending on ice, prey, and season

Question 4 · multiple choice

A motion camera records a Polar bear. Which description should appear in the observation notes?

walks over ice and swims with powerful forelimb strokes walks in organised trails carrying leaf pieces overhead wades, swims, and flies in long formations walks, sprints briefly, swims, and follows scent trails

Question 5 · multiple choice

Which adaptation would a biologist correctly connect to a Polar bear?

a flexible leathery shell and heat-saving circulation allow deep cold dives black skin and dense water-repellent fur help absorb and retain heat keeps skin and mouth surfaces moist to exchange gases out of water branched body hairs collect pollen while a honey stomach carries nectar

Question 6 · multiple choice

What would a researcher most reasonably record during the breeding cycle of a Polar bear?

several females may lay eggs in one communal scrape guarded by dominant adults eggs are laid on rock and guarded and fanned by the male mothers give birth in snow dens and emerge months later with cubs females bury clusters of eggs in beach sand

Question 7 · multiple choice

How is a Polar bear most likely to organise its everyday social life?

forms large daytime schools around some islands and seamounts mostly solitary but may shelter in groups usually seen alone or in pairs outside family periods mostly solitary except for mothers, cubs, and temporary gatherings

Question 8 · multiple choice

A habitat manager explains why the Polar bear matters. Which explanation is accurate?

transfers marine nutrients onto land through remains and waste controls rodents and supplies prey for raptors and mammals controls crustaceans and recycles shells around dens pollinates flowers and feeds many predators despite chemical defence

Question 9 · multiple choice

Which field observation would show a Polar bear defending itself?

clings strongly and can regrow lost arms if enough central tissue remains relies on camouflage, size, and strong forepaws when threatened drops from the web, hides, or wraps prey rapidly uses precise stomps rather than putting its face close to dangerous prey

Question 10 · true false
