Polar Bears and Their Environment

What is the primary dietary requirement for polar bears to maintain their large size?

• High protein intake

• High carbohydrate intake

• High fat intake

• High fiber intake

Why do polar bears and penguins never meet in the wild?

• They live in different hemispheres

• They are separated by mountain ranges

• They have different dietary needs

• They are active during different seasons

What prevents most penguin species from living in the Northern Hemisphere?

• Unsuitable nesting sites

• Predators in the north

• Inability to cross warm climates

• Lack of food sources

If polar bears and penguins lived in the same environment, what would be a major threat to penguins on land?

• All of the above

• Leopard seals

• Arctic foxes

• Polar bears

How do polar bears primarily hunt their favorite prey, seals?

• By digging into their dens

• By ambushing them on sea ice

• By waiting at riverbanks

• By chasing them in the water

What is the primary reason polar bears are considered ambush predators?

• They hunt in packs

• They surprise seals at breathing holes

• They rely on speed to catch prey

• They use camouflage to blend in

What is a significant consequence of melting sea ice for polar bears?

• Improved hunting conditions

• Increased competition with penguins

• Longer periods spent on land

• More abundant food sources

What alternative food source have polar bears started to exploit due to climate change?

• Insects

• Bird eggs

• Small mammals

• Fish

Why is hunting bird eggs not an optimal strategy for polar bears?

• Eggs are too small to provide enough energy

• Polar bears are not good at finding eggs

• Birds defend their nests too aggressively

• Eggs are only available in certain seasons

What is a major challenge for polar bears as the Arctic continues to warm?

• Loss of natural camouflage

• More frequent encounters with humans

• Decreased availability of seals

• Increased competition with other predators
