Do grizzly bears or polar bears have better adaptations for changing environment?

Explanation:

polar Bears have better adaptation in the changing environment

Explanation:

The polar bear's life cycle is closely tied to sea ice. Polar bears rely on the ice to travel, hunt seals, breed, and in some cases, den. Scientists believe polar bears are unlikely to survive if ice-free periods exceed their fasting ability (220 days), especially in areas that lack alternate marine mammal prey.

Polar bears are strong swimmers and divers, a characteristic that allows them to swim from one ice floe to the next. But there’s a limit to how far they can swim. Long swims are especially dangerous to young cubs.

some fungi obtain their nutrients from a living host (plant or animal) and are called most biotrophic fungi have fairly narrow host ranges—they are specialized on a limited called rhizomorphs that allow the fungus to grow from one tree to another. ascospores are formed inside a sac-like structure called an ascus. so your answer is a
