Nitrogen recycling refers to the process by which nitrogen circulates through the ecosystem. It involves four key entities: plants, animals, bacteria, and the atmosphere. Plants absorb nitrogen from the soil in the form of nitrates. Animals consume plants and convert the nitrogen into proteins. Bacteria in the soil decompose dead organisms and waste products, releasing nitrogen back into the soil. The atmosphere contains a vast reservoir of nitrogen that can be fixed by certain types of bacteria and made available to plants. This intricate cycle ensures the continuous availability of nitrogen, a vital nutrient for all living organisms.
