What interactions supply energy to the Earths biosphere?

The Earth's biOSphere is primarily energized through interactions involving sunlight, which is harnessed by plants during photosynthesis to produce organic matter. This process forms the foundation of the food chain, supporting various life forms. Additionally, geothermal energy from the Earth’s interior and chemical energy from nutrient cycling also contribute to the biOSphere's energy supply. Together, these interactions sustain ecosystems and enable life to thrive on the planet.
