The basis of this mutualistic, symbiotic relationship can be described by which of the following statements? Actually, all of these are accurate descriptions of the symbiosis between rhizobia and plants. Rhizobia help the plants expand access to minerals in the soil while the plant protects the rhizobia from predators and viruses. The rhizobia will conduct photosynthesis which allow the plants to access carbon without having to deplete their own energy to do carbon fixation. The rhizobia fix nitrogen for the plant while the plant fixes carbon which it shares with the rhizobia. The rhizobia will produce oxygen which will help the soil to maintain oxygenation and thus avoid pathogens.arrow_forward
