According to studies, the arctic fox populations in the tundra regions are being threatened by incursion s of res fox populations from the south. based on current patterns in climate change, what is the most likely reason for the migration of red fox to the tundra?

The correct answer would be option D.

Tundra is a biome in which trees growth is hindered by the low temperature of the region.

The tundra region remains cover with ice until summer appears.

The vegetation may include shrubs, grasses, lichens et cetera.

Due to current environmental changes, there is an increase in tree cover in the region.

The increased tree cover attracts the red foxes from the south.

As red foxes are omnivores in nature, an increase in tree covers would increase the amount of food available. For example, berries, fruits, grasses, birds, squirrels, mice, and rabbits.
