How foes Fungus kill trees?

Fungi can kill trees by invading their tissues, disrupting essential functions like water and nutrient transport. They may cause decay by breaking down wood and bark, leading to structural weakness. Some fungi produce toxins that can damage or kill tree cells, while others can trigger diseases that weaken the tree's defenses, making it more susceptible to other stressors. The cumulative impact of these factors can ultimately lead to the tree's death.
