Answer 2

Answer:

beans

Explanation:

Nitrogen fixing plants gain help from a common bacteria called Rhizobium. The bacteria infects legume plants such as peas and beans and uses the plant to help it draw nitrogen from the air.

The bacteria converts this nitrogen gas and then stores it in the roots of the plant. When the plant stores the nitrogen in the roots, it produces a lump on the root called a nitrogen nodule. This is harmless to the plant but very beneficial to the soil.
