What is an essential behavior beavers exhibit in preparation for winter?

Building larger dams
Harvesting and submerging tree branches
Storing food above water
Moving to warmer climates

The correct answer is: Harvesting and submerging tree branches

Beavers exhibit the behavior of harvesting and submerging tree branches as an essential preparation for winter. This behavior is crucial for their survival as it enables them to create a food cache. During the autumn months, beavers gather branches, twigs, and other biomass from trees and shrubs, then they cut and transport these resources to their underwater storage area near their lodges. By submerging the branches, the beavers keep them submerged in cold water, preventing them from freezing. This allows the beavers to access food even in the winter months when the surface is frozen and foraging becomes difficult. This behavior is a strategic adaptation to ensure they have adequate nutrition during the winter when food sources are scarce.
