The Unified Cycle from Stellar Nucleosynthesis to Food Crop Systems: Gratitude to Earth for Underground Tubers, Sweet Potato Leaves as Source of Energy-Nutrition

Solar energy not only supports primary productivity on Earth but also con- nects biological systems to the broader structure of the universe. This paper presents a scientific synthesis linking stellar nucleosynthesis, photosynthesis, trophic nutrition energy transfer, and ecological process, with a focus on food crop systems including tuber crops. We highlight how bio-essential elements, formed in celestial objects, are transformed through plant metabolism into edible nutritional energy and...
