A mutualistic relationship between legumes and soil bacteria in the
genus Rhizobium. The Rhizobia can fix nitrogen gas when the
symbiosis is achieved. They can't fix nitrogen in the free-living state,
however!
Fixed nitrogen is obtained by the legume and the Rhizobium gets a
nice place to live with all of the amenities!. This includes glucose,
water and minerals. This is an extremely important relationship
because Nitrogen is usually the most limiting element in terrestrial
ecosystems

Although termites can physically chew and ingest wood, they are
incapable of chemically digesting cellulose into sugars. They rely on
intestinal flagellates, Trichonympha spp. which are capable of
digesting cellulose. These genera of flagellates reside in the hindgut
of termites and provide nutrition for them. They are not found
anywhere else in nature.
