Solution
Dear student.
Sunn hemp is a leguminous plant.
Rhizobiumbacteria found in the root nodules of leguminous plants like pulses enables them to fix nitrogen. It lives in symbiotic association with plants and fixes the atmospheric nitrogen in leguminous plants. It converts the atmospheric nitrogen into absorbable forms such as nitrate and nitrite so that plants can take them up from the soil.
