What eats what in the Arctic?
The Arctic Ocean is teeming with fish. Some of the most common include salmon, mackerel, char, cod, halibut, trout, eel, and sharks. Arctic fish eat krill and plankton and are eaten by seals, bear, other large and small mammals, and birds.
How do plankton survive in the Arctic?
Lipid storage and diapause allow zooplankton species to survive the harsh Arctic winter conditions. Both of these species are very abundant in the Arctic, and their lipids make them an energetically rich food source for upper trophic levels, such as fish, seabirds, and whales.
Do polar bears eat plankton?
Both seals and whales eat fish and other creatures that get their energy from tiny creatures called zooplankton, which in turn eat the algae on sea ice. One of the polar bear’s favorite meals, the ringed seal, eats a variety of fish and shrimp that munch on algae-eating plankton. In summer as ice melts, the algae sink.
Do polar bears eat snow?
Polar bears will also sometimes eat snow, but usually not in great quantities as it requires too much energy to melt it. In fact, eating snow tends to be something the bears mainly do when they want to cool down (after sparring or on a sunny day).
Do polar bears drink ocean water?
To get drinking water the polar bears would have to eat snow, or eat specific bits of icebergs (sea ice and sea water are too salty and would make them thirstier than they started out). Eating snow or ice would lower the polar bear’s body temperature, which is not a good idea.
Do polar bears sweat?
Adult polar bears spend a lot of time on their own and travel over huge distances. One way bears find each other is by smell – polar bears have a sweat gland on the bottom of their feet that leaves a distinctive scent.
Do polar bears scream when pooping?
It’s certainly possible that a polar bear has grunted, groaned, or even roared while defecating, but it is not common (or necessary) for a polar bear to yell while defecating. This is just an old joke that has been repeated so many times some people have come to accept it as real.
Can a polar bear survive in hot weather?
Can Polar Bears Survive in the Heat? No, definitely not! Polar bears have quite many adaptations to survive in extreme cold weather. They cannot survive in warm weather—not even for one day.
Who would win in a fight a polar bear or a gorilla?
