Question

explain,how rhizobium bacteria and leguminous plants help each other in their survival

Answer 1

Rhizobium converts atmospheric nitrogen into the soluble form , which can be then taken in by the leguminous plants.However since Rhizobium cannot prepare their own food , it  establishes in the roots of the plant and provide them with nutrients. Plants in turn provide it with food and shelter. Thus there exists a symbiotic relationship between the Rhizobium and leguminous plants.
