Final answer:
Organic farming is more energy efficient because it reduces the use of heavy machinery and fossil fuels, promoting a sustainable approach.
Step-by-step explanation:
Organic farming is more energy efficient because it reduces the use of heavy machinery and fossil fuels. In conventional farming, heavy machinery is used for tasks such as preparing the seedbed, controlling weeds, and harvesting the crop. However, the use of heavy equipment can cause soil compaction and disrupt natural soil organisms. In contrast, organic farming practices focus on reducing unnecessary input use and promoting soil fertility and health, which results in a more energy-efficient and sustainable approach.
