Answer 1

in roots of leguminous plant such as beans and peas there is a nitrogen fixing bacteria called rhizobium which fixes the atmospheric nitrogen into the soil thus increasing the fertility of the soil

Answer 2

They contain symbiotic bacteria calledrhizobia within the nodules, producing nitrogen compounds that help theplant to grow and compete with otherplants. When the plant dies, the fixed nitrogen is released, making it available to other plants and this helps to fertilize the soil
