Biotic Factors
Biotic Factors are factors in an organisms habitat that interact with the organism
Orca/Killer Whale (Orcinus Orca)-One of the most efficient hunters in the Arctic Ocean, these organisms are the apex predators in their ecosystem, lacking natural predators in their habitat. These predators hunt in pods, drastically improving their effectiveness. Orcas commonly live to around 50-70 years, and one orca has been recorded to live for 103 years. On the other hand, captured orcas only live to around 20-30 years with the oldest only living for 50 years.

Polar Bears (Ursus Maritimus)-Perhaps the most famous out of all Arctic organisms, the polar bear is the largest land-based carnivour. Although born on land, polar bears spend most of their lifetime in the ocean hunting for seals, their main source of food. These bears have a life expectancy of around 25 years, with older bears too weak to hunt and eventually starve to death.
