Lichen
Lichen explained in an easy to understand way:
Imagine you're trying to make a perfect sandwich, but you're missing the bread and your friend is missing the filling. This situation is similar to how a lichen functions, where a fungus and a green alga each provide what the other lacks to thrive. Just as you and your friend combine your resources to create a satisfying meal, the fungus offers structure and protection while the alga provides food through photosynthesis, creating a mutually beneficial partnership.
