Polar bears are at the very top of the pyramid. They are an apex predator.
There is no energy pyramid on the continent, because there is no food chain on the land.However, the Southern Ocean which surrounds the continent, has the shortest food chain on Earth, based on Antarctic Krill, properly Euphausia superba. The top of the ocean's food chain are protein-consuming whales and seals.
A bear would be considered a tertiary consumer in an energy pyramid. It obtains energy by consuming primary and secondary consumers, such as fish and berries. Bears have a high energy requirement due to their large size and active lifestyle.
the polar bear is the world largest predator found on land.
The polar bear is a tertiary consumer - third lever.
'walking hibernation' means that the bears metabolism alters to a hibernation-like state which facilitates significant energy consercation. They remain active, but rely on stored fat for energy. This is a trait no other species of bear posesses.when the polar bear enters walking hibernation, their metabolism goes to a hibernation-like level. the polar bear remains active, but relys on stored body fat. the polar bear is the only bear that does this.
A polar is a fourth-level or tertiary consumer. This means that it is at the top of the food chain. Primary consumer in a polar bear's habitat are things like zooplankton. Secondary consumers are the fish that eat the plankton and third or tertiary consumers are the seals that eat the fish.
I don't know try to find a walkthrough
polar bears need to live, so they have to get energy from other animals.
Lvl 18 u can buy it
The polar bear liver contains high levels of vitamin A because it helps the bear's body store energy and adapt to its cold environment.
a polar bear is both slow and fast moving its slow when trying to catch its prey and fast to move away from a predator
why does the polar bear helps the polar ice
