Fungi of the phylum basidiomycota form mycorrhizal associations with orchids, a type of flowering plant. how do these associations benefit both the fungi and the orchids? a. the orchids receive water and oxygen from the fungi, while the fungi receive food and minerals from the orchids. b. the orchids produce decaying material for the fungi, while the fungi provide structural support to the orchids. c. the orchids release enzymes to break down sugar for the fungi, while the fungi fertilizes the soil surrounding the plant. d. the orchids gain nutrients and carbon dioxide from the fungi, while the fungi gain oxygen and sugar from the orchids.
