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. what kind of a relationship is exhibited in this example? a. the fungi share a mutualistic association with the trees. b. the fungi are a parasite for trees. c. the fungi share a commensal association with the trees. d. the fungi are predators for the trees.

The option A is the correct option. The fungi share a mutualistic association with the trees.

Mutualism or interspecific cooperation is the way two organisms of different species exist in a relationship in which each individual fitness benefits from the activity of the other. And in this case, both plant and fungi are benefited by each other. The plant provides food and habitat for the living of fungi and fungi, in turn, decompose dead organic matter to provide simple compounds to plants.

While in commensalism only one either plant or fungi can be benefited. And it is also not a parasitic interaction.
