Mycorrhizae are associations formed by fungi that grow on the roots of trees. These fungi penetrate into the roots of the trees. The trees produce energy through photosynthesis and share it with the fungi. The fungi act as decomposers, breaking down dead organic matter to provide nutrients for the trees to grow. The kind of relationship exhibited here is, A. The fungi share a mutualistic association with the trees.
