Mutualism is a relationship among two animal varieties, where two species lives in close relationship with one another. In this relationship both the species are profited.
The given circumstance, is an illustration of mutualistic relationship of the contagious species with the tree. This is a direct result of the way that the parasitic species furnishes trees with supplements after the cycle of deterioration, that are vital for the development of the trees. Consequently the parasitic species gets carbs delivered by photosynthesis from the foundations of the trees. Subsequently, both the species are profited thus, it is a mutualistic affiliation.
