The elemental compound produced during photosynthesis is glucose (C6H12O6), along with oxygen (O2) as a byproduct. During photosynthesis, plants, algae, and certain bacteria harness sunlight, typically using chlorophyll, to convert carbon dioxide (CO2) from the atmosphere and water (H2O) from the soil into glucose. This process not only provides energy for the plant but also serves as a foundational element of the food chain, as glucose is utilized by various organisms for energy. The oxygen produced is released into the atmosphere, contributing to the breathable air necessary for most life forms on Earth.
