Chicken fir is actually a mushroom planted by termites. Where there are termites, there will be termites' nests if you dig down. And there will be a pile of false roots at the bottom of the chicken fir tree, which will be connected to the termite nest. ?

Traditionally, the relationship between termites is called symbiotic relationship. Termite digest can provide nutrition for termites, and termites can secrete some biotin, so that harmful miscellaneous bacteria will not grow near termites' nests. ?

In fact, not only termites, but also many ants have this symbiotic behavior with fungi, such as the famous leaf-cutting ants. However, a more detailed study of leaf-cutting ants recently showed that the relationship between ants and fungi seems to go beyond the simple symbiotic relationship.

Because the behavior of leaf-cutting ants moving back to their nests after cutting leaves is too complicated to be unintentional. They will treat the leaves in a very complicated and orderly way, such as spraying exudate on the leaves and spreading fungal spores. During the whole growth cycle of fungi, they will be regularly fertilized and carefully cared for. ?

In fact, dancing with fungi is a very dangerous occupation. We know that some fungi will invade ants' bodies and manipulate them into zombies. But these mushroom-growing ants have generally evolved immunity to these terrible fungi.
