Final answer:
Legumes are plants that have the ability to fix atmospheric nitrogen and benefit other plants by releasing nitrogen into the soil.
Option C.
Step-by-step explanation:
Legumes are plants that have the ability to fix atmospheric nitrogen due to a symbiotic relationship with bacteria found in their root nodules.
Examples of legumes include alfalfa, clover, peas, beans, lentils, and peanuts. These plants play a crucial role in agriculture as they not only fix nitrogen for their own use but also release nitrogen into the soil, benefiting other plants.
In addition, legumes can perform nitrification, converting organic nitrogen to nitrites and nitrates, which is beneficial for the soil.
One advantage of rotating crops like corn and soybeans is that it helps break the cycle of monoculture, where the same crop is grown repeatedly.
Monoculture can deplete soil nutrients and attract plant pests. By alternating between different crops, such as corn and soybeans, farmers can maintain soil fertility and reduce the risk of pests and diseases.
Overall, legumes are important nitrogen-fixing plants that contribute to sustainable agriculture, soil health, and crop rotation practices.
