What resources does the reindeer use to survive?

Reindeer primarily rely on lichen, particularly reindeer moss, as their main food source during the harsh winter months. In addition to lichen, they consume grasses, herbs, and leaves during the summer. Their adaptations, such as large hooves for traversing snow and specialized fur for insulation, also play a crucial role in their survival in cold, arctic environments. Furthermore, they utilize migratory patterns to access different food sources throughout the year.
