Hi, I'm a Polar Bear.
This is my Food Chain:
Decomposers -> Microplankton -> Plankton -> Small fish -> Medium fish -> Polar Bear.
Here is my Levels of Organization:

Keystone Species: The arctic fox is one of keystone species of the arctic tundra. Primarily, it is prey for polar bears, wolves, and snowy owls. If the arctic fox was removed of this ecosystem, the populations of the predators would decline drastically, due to lack of food. Another keystone species are the arctic seals which include: ribbon seals, ringed seals, harp seals, bearded seals, hooded seals and spotted seals. They are prey to Polar bears, Orcas and Sharks. If these species of seals we nonexistent, it would drastically change the ecosystem resulting in other species merging into extinction, or learning to adapt. Seal are a main food source for us mainly, but they are the hardest to catch due to their slick bodies and they normally stay near a body of water resulting in a fast getaway.
Habitat: I live in the Arctic, and nowhere else in the world. I eat meat and love the taste of seal, especially fat because that gives me the most energy and heat. My habitat is the edges of pack ice where currents and wind interact because that means I’m right next to the sea, where I get my food. The ice helps me blend in to prey on my food. I also live in the Polar climate zone. I occupy the Tundra biome. Polar bears have evolved so that they don't need to drink free water. I get my water from the chemical reaction that breaks down fat. This is why my diet is high in fat but low in protein.
How Humans Can Help: Everyone is capable of joining in the efforts to help save my species from extinction, and my biome from extinction. Primarily everyone can raises awareness of pollution that constantly kills not only my biome but also my own kind. Nearly 600 polar bears die per year a plethora of which die of destruction to the biome. Also polar bears have been hunted since the beginning of mankind, wanted for their fur and meat. Although the amount of polar bears killed due to hunting is considerably lower it still remains the largest sources of polar bears death. Lastly you can leave no trace, oil spills happen all around the tundra biome, but no efficient method of containing, or removal of the oil has been made. Any help you are able to make could be the difference of life and death for myself and all of the other biotic factors in the tundra biome.
Density Independent:
Adult polar bears have no natural predators except other polar bears. Cubs less than one year old sometimes are prey to wolves and other carnivores. Newborn cubs may be cannibalized by malnourished mothers or adult male polar bears.
Density Dependent:
Ice in the Arctic melts, reducing land for shelter, and making more room (making it harder to find) fish and seals.
Human Impact: The polar bears are being influenced by the humans because of climate change. This climate change melts ice, which polar bears rely on to hunt for prey. When polar bears don’t get enough food intake, they get diseases. When the polar bears have diseases, it reduces the amount of cubs they can have.

Predation: Most of my kind primarily feed on ringed seals and bearded seals, but they are also known to eat walrus, beluga whale and bow-head whale carcasses, birds' eggs, and in extreme vegetation. Sometimes I travel long distances in search of prey
