Answer 1

Answer:

The bacteria fix atmospheric nitrogen and make it available to the plants. On the other hand, Rhizobium receives nutrition from the plant in the form of organic acids.

Answer 2

Answer:

The symbiosis between rhizobia soil bacteria and legumes is facultative and initiated by nitrogen starvation of the host plant. ... In this mutualistic symbiosis, the bacteria provide nitrogen sources for plant growth in return for photosynthates from the host.
