\nThe percentage of solar radiation absorbed by all green plants for the process of photosynthesis is about 1%.
\n<\/section>\n
\nEcological studies show that only a small fraction of the total solar energy incident on the Earth’s surface is captured by producers (green plants) and converted into chemical energy through photosynthesis. This efficiency is typically stated as being around 1%. This absorbed energy forms the base of most ecosystems, supporting all subsequent trophic levels.
\n<\/section>\n
\nWhile plants absorb some portion of the sunlight (especially in the red and blue wavelengths), much of the incident light is reflected or transmitted. Furthermore, not all absorbed energy is converted into biomass; a significant portion is lost as heat or used by the plant for its own metabolic processes (respiration). The 1% value refers to the efficiency of conversion of incident solar energy into net primary production.
