Final answer:
The arctic fox is an omnivore, consuming both plant-based and animal-based food and is well adapted to its environment with features like seasonal fur changes.
Step-by-step explanation:
The arctic fox is an omnivore, which means it is an animal that consumes both plants and animals. The arctic fox is well adapted to its harsh environment and has features like changing its coat color with the seasons and having longer fur in winter to trap heat. It is a complex animal that showcases the close relationship between an animal's form and its function.
As an omnivore, it falls on a continuum between herbivores, which eat only plants, and carnivores, which eat only animals. In the changing climate of its habitat, the arctic fox's diet also changes; for example, they might eat more animals when they are available and switch to plants or berries when animal prey is scarce.
