(i) Mycorrhizae are the mutualistic relationship between fungi and roots of higher plants. The fungus helps in mineral nutrition of the plant with which they are associated and obtains, in turn, carbohydrates from the plant.
(ii) Nitrogen-fixing bacteria, Rhizobium, live in the root nodules of legumes where the bacterium derives nutrition from the host plant but fixes the atmospheric nitrogen and makes it available to the plants.
