The X is rhizobium

      Y is  legumes like pea ,bean or gram.

Explanation:

• The result of this symbiosis is to form nodules on the plant root , whithin which the bacteria can convert atmospheric nitrogen into ammonia that can used by plants.
• Rhizobia are  bacteria that fix nitrogen by establishing inside the root nodules of legumes (fabaceae) . the express genes for nitrogen fixation , rhizobia require a plant host they could not independently fix nitrogen .
• In general they are gram negative ,non sporulating rods , gram negative.
• Rhizobia is found in soil and after infection it forms nodules in the legume where they fix nitrogen gas from the atmosphere turning it to a more useful form of nitrogen .
• Once legumes dies the nodules breackdown and releases them in the soil.
