If a legume inhibits the growth of other plants around it by using noxious chemicals,

Question

Quizplus · Accepted Answer

Legumes are able to fix nitrogen in the soil through their symbiotic relationship with bacteria. The chemicals that inhibit the growth of other plants are released by the legume's roots and are known as allelochemicals. While these chemicals may limit the growth of other plants, they do not harm the legume itself. In fact, the nitrogen fixation by the legume and its bacteria can actually increase the amount of nitrogen in the soil over time, making it a beneficial addition to the ecosystem.
