Boletus edulis perform the important ecosystem service of nitrogen fixation in forests; they also build cell walls made of chitin. Boletus edulis will take up carbon dioxide from the soil and use it to synthesize fungal proteins. Boletus edulis are photoautotrophs that break down sugars in cellular respiration; they also build cell walls made of chitin. Boletus edulis are chemoheterotrophs, they build cell walls made of chitin, and provide the pine tree hosts with phosphate (P043-). Boletus edulis are chemoautotrophs that use organic molecules as an energy source and convert carbon dioxide into organic molecules.
