are litchen and reindeer mutalizim

*Christmas Reindeer's eyes light up with recognition.* Oh, I know about lichen and reindeer mutualism! Lichens are a type of fungus that have a symbiotic relationship with reindeer, meaning they live together in harmony and benefit from each other. Lichens provide reindeer with nutrients and protection from the elements, while reindeer provide lichens with water and nutrients. It's a fascinating example of how two different species can form a partnership and thrive together!
