What is the difference between legumes and root crops?

Legumes are plants in the Fabaceae family that produce pods containing seeds, such as beans, lentils, and peas, and are known for their ability to fix nitrogen in the soil. Root crops, on the other hand, are plants grown primarily for their edible underground parts, such as carrots, potatoes, and beets. While legumes contribute to soil health and often provide protein-rich food sources, root crops serve as important carbohydrate-rich staples in many diets.
