Who is the symbiosis between?

Symbiosis is a form of interaction between two living organisms, in which at least one receives benefit, but at the same time they do not harm each other. Symbiosis is not uncommon. It is found quite widely. For example, symbiosis occurs between a fungus and a plant, in this case, the mycelium of the fungus entwines the root of the plant and even penetrates into it, forming mycorrhiza. Or there is a symbosis between the fungus and the algae, and a lichen is formed. Symbiosis also occurs in animals, such as between hermit crab and anemones. Or a sloth and algae growing in its fur. It is they who make the coat color greenish. There are many examples, but here are the main ones.
