Answer:
The bacteria take gaseous nitrogen from the air in the soil and feed this nitrogen to the legumes; in exchange the plant provides carbohydrates to the bacteria. This is why legume cover crops are said to "fix" or provide a certain amount of nitrogen when they are turned under for the next crop or used for compost.
