How does the nature of contacts between partners in cooperation differ from contacts in symbiosis? What effect does their cohabitation with cap mushrooms have on trees?

Symbiosis is a mutually beneficial relationship between living organisms, in the process of which both benefit. Cooperation is a kind of “optional” symbiosis, that is, during cooperation, organisms can cooperate to achieve a common goal, or they can exist separately from each other.

Very often symbiosis occurs between trees and cap mushrooms (aspen-boletus, apricot-boletus). In this symbiosis, fungi entwine the roots of trees and provide the tree with water and nutrients from the soil, and the tree provides carbohydrates to the fungus. At the same time, both grow more and adapt better to the surrounding conditions.
