Question
How does the speech introduce the polar bear survival topic?
Page 2
Answer
Polar bears are dying thanks to us. Let me explain why and how but first, what is a polar bear?
2
Question
Which characteristics establish polar bears as powerful predators?
Page 3
Answer
Polar bears are one of the largest apex predators. How do they survive in the world?
3
Question
How do polar bears maintain body warmth in their habitat?
Page 3
Answer
They keep warm in their icy cold habitat with insulation. Polar bears have one thick layer of blubber (animal fat) and two layers of fur.
4
Question
Which unusual properties characterize polar bear fur?
Page 3
Answer
An interesting fact About their fur is that their fur hairs are not white they are actually transparent and hollow.
5
Question
How do the fur and blubber layers support survival?
Page 3
Answer
These layers help them keep warm in the cold. It works like a natural body wetsuit like a heating mechanism.
6
Question
How do black skin and transparent fur interact with sunlight?
Page 3
Answer
Polar bears have black skin attracting the sun, but how does the sun's heat rays get through the fur? As I told you, the fur hairs are transparent . This lets the heat get through the fur Interesting isn't it!

Question
Which dietary classification applies to polar bears?
Page 4
Answer
Polar bears are carnivores , which means they mainly eat meat.
8
Question
Which prey are identified as polar bears’ favorite food?
Page 4
Answer
Their favourite food is seals, especially ringed and bearded seals. The way bearded seals do not literally have a chin beard.
9
Question
Why are seals important to polar bear survival?
Page 4
Answer
Seals provide them with a lot of fat and energy to survive in the cold arctic environment.BRRRR.
10
Question
How do polar bears hunt seals near sea ice?
Page 4
Answer
Polar bears are excellent hunters and often wait patiently by breathing holes in the sea ice for a seal to come up for air (breathing holes are vertical tunnels in the sea ice that are kept open). Isn't that smart. I don't think we would think of that.
11
Question
Which alternative hunting method is used on resting seals?
Page 4
Answer
They can also hunt seals by sneaking up on them while they are resting on ice, BOO.
12
Question
How does opportunistic hunting broaden the polar bear diet?
Page 4
Answer
Although seals are their main food source, polar bears are opportunistic hunters meaning they will eat other animals when they can. Rude. Their diet can include walruses, fish ,sea birds ,reindeer and sometimes eggs (they mainly hunt reindeer during spring and late summer/autumn).
13
Question
When do polar bears mainly hunt reindeer?
Page 4
Answer
(they mainly hunt reindeer during spring and late summer/autumn).
14
Question
How do alternative foods compare with meat energetically?
Page 4
Answer
They also eat plants, berries, and other foods,especially when their usual prey is difficult to find, but these foods do not provide nearly as much energy as meat do.
15
Question
Why must polar bears consume large amounts of food?
Page 4
Answer
Polar bears need to eat a large amount of food because they use a lot of energy to stay warm and travel across the arctic.
16
Question
How does seal-derived fat support polar bear survival?
Page 4
Answer
The thick layer of fat ewwww they get from seals is especially important because it helps them keep warm in the freezing cold temperatures, and provides energy when food is scarce. This makes their diet a very important part of their survival in the harsh arctic environment.
17
Question
Which environmental changes threaten polar bear survival?
Page 5
Answer
Polar bears are uniquely adapted to the harsh arctic environment. This means sudden environmental changes could affect them such as climate change and heat rising.
18
Question
Why is sea ice essential to polar bear life?
Page 5
Answer
These environmental factors could also affect them because polar bears rely primarily on sea ice as a platform for traveling, hunting, breeding and denning, because they depend on such a specialised ecosystem, changes in the environmental conditions could directly impact their survival, body conditions and reproduce rates (meaning there will not be as much cubs born each year).
19
Question
Why is protecting polar bears important for the Arctic ecosystem?
Page 6
Answer
It is critical to keep polar bears protected and safe because they are an important part of the arctic ecosystem and are one of the animals most affected by climate change.
20
Question
How do rising temperatures alter the sea-ice cycle?
Page 6
Answer
Polar bears rely on sea ice to hunt seals, travel and sometimes rest but, the rising temperatures are causing the ice to melt earlier and form later each year.
21
Question
How does earlier melting affect polar bear feeding?
Page 6
Answer
This makes it harder for polar bears to find enough food and force them to travel further to survive.
22
Question
How do polar bears influence the Arctic food chain?
Page 6
Answer
Protecting polar bears also helps protect the wider arctic food chain, as polar bears regulate the seal population in a way of hunting them and eating them.
23
Question
Which conservation actions can support polar bear survival?
Page 6
Answer
By reducing climate change, protecting their habitats, by preventing pollution and making sure they have enough space to live and hunt, we can help polar bears survive for future generations.
24
Question
Why does polar bear protection extend beyond the species itself?
Page 6
Answer
Keeping polar bears safe is not only important for their sake but also for maintaining a healthy and balanced arctic ecosystem!
