Question

Explain the role of rhizobium bacteria in fixing the atmospheric nitrogen for 1 in brief????

Answer 1

In a symbiotic relationship with the soil bacteria known as 'rhizobia', legumes form nodules on their roots (or stems, see figure below) to 'fix' nitrogen into a form usable by plants (and animals). ... Plants cannot fix nitrogen on their own, but need it in oneform or another to make amino acids and proteins.
