AnswerClick to flip back
A
Nitrogen
💡 Explanation:
  1. Leguminous plants contain symbiotic bacteria called Rhizobia within nodules in their root system, producing nitrogen compounds that help the plant to grow and compete with other plants.
  2.  This bacteria absorbs molecular nitrogen from the atmosphere and converts it into inorganic nitrogenous compounds which is used for organic nitrogenous compounds synthesis.
  3. When the plant dies, the fixed nitrogen is released, making it available to other plants and this helps to fertilize the soil.
