Does polar bears use cellular respiration?
Respiration occurs in this polar bear and in all other animals too. During respiration, energy is created to fuel the different processes necessary to support life. In addition to making useful energy, respiration makes carbon dioxide and water as waste products.
What do polar bears use their energy for?
Processing body fat to gain metabolic water (physiological) – Polar bears store a lot of fat which they use for energy in the process combining it with oxygen to release carbon dioxide and metabolic water.
Do polar bears require sunlight?
The polar bear loves and is well adapted to the cold and icy climate of the Arctic. They have a dense fur that has hollow air-filled hairs which insulate the polar bear from the frigid weather conditions. The fur also allows them to absorb the sunlight which also keeps them warm.
What allows polar bears to survive?
Arctic Adaptations Polar bears live in one of the planet’s coldest environments and depend on a thick coat of insulated fur, which covers a warming layer of fat. Fur even grows on the bottom of their paws, which protects against cold surfaces and provides a good grip on ice.
What type of cells are polar bears made of?
All polar bears have nerve cells, blood cells, muscle cells, and skin cells. These cells are the basic cells that they have. The number of cells that a polar bears has depends on its size. Polar bears are the largest land carnivores and they have black skin and colourless hair.
Why do polar bears have 42 teeth?
Polar bears have 42 teeth, which they use for catching food and for aggressive behavior. Polar bears use their incisors to shear off pieces of blubber and flesh. Canine teeth grasp prey and tear tough hides.
Do polar bears eat plants?
Food Preferences & Resources Polar bears feed mainly on ringed and bearded seals. When other food is unavailable, polar bears will eat just about any animal they can get, including reindeer, small rodents, seabirds, waterfowl, fish, eggs, vegetation (including kelp), berries, and human garbage.
Is a polar bear a carnivore herbivore or omnivore?
Unlike other bear species, polar bears are almost exclusively meat eaters (carnivorous). They mainly eat ringed seals, but may also eat bearded seals. Polar bears hunt seals by waiting for them to come to the surface of sea ice to breathe. They also eat walruses and whale carcasses.
Are polar bears carnivores herbivores or omnivores?
Unlike other bear species, polar bears are almost exclusively meat eaters (carnivorous). They mainly eat ringed seals, but may also eat bearded seals. Polar bears hunt seals by waiting for them to come to the surface of sea ice to breathe.
What is the scientific name for polar bear?
Polar bear/Scientific names
The polar bear’s Latin name, Ursus maritimus, means “sea bear.” It’s an apt name for this majestic species, which spends much of its life in, around, or on the ocean–predominantly on the sea ice.
How do polar bears change as they grow?
During life in the maternity den, the polar bears will change and grow as the months go by. Within the first month, a polar bear cub will open its eyes. After two months, polar bears will learn to walk around their den. Their bodies have also begun to develop thick fur and their teeth are emerging by this time.
Do polar bears have a hump?
The polar bear (Ursus maritimus Phipps, 1774) is, on average, the largest of the eight species of bears found worldwide and is completely white. Typically, the body is stocky, lacks a shoulder hump, and has a longer neck in relation to the rest of the body than other ursids.
Why is photosynthesis important to the polar bear?
The Polar Bear. The chemical equation for photosynthesis is 6CO2 + 6H2O –> C6H12O6 + 6O2. This is important because plants, such as cushion plants in the Arctic, are producers by doing this method. During the day, they take in light energy, which is called the light reaction, and change it into chemical energy.
Where does the polar bear get its chemical energy from?
During the day, they take in light energy, which is called the light reaction, and change it into chemical energy. They do this with the chlorophyll, which is located in the chloroplast, which is in a leaf cell, which makes up a leaf.
How are photosynthesis and respiration related to each other?
Photosynthesis requires energy, and a plant’s chloroplasts absorb solar energy to fuel these reactions. Photosynthesis can only happen during the day when sunlight is available. Respiration, on the other hand, is the breaking down of sugars (and oxygen) to provide energy for plant growth.
What kind of organelle does a polar bear have?
An organelle called mitochondria is the thing that breaks down the food particles into sugars that will be used for cells. Since polar bears are apex predators in the Arctic, they will break down all of the nutrients that were contained in the food they ate, whether it be a seal, or other things if they couldn’t find any food sources.
