"In most ecosystems, sunlight (or solar energy) is the initial source of energy absorbed by producers through the process of photosynthesis." In a typical terrestrial ecosystem, the producers, who are capable of such photosynthesis, are the only organisms capable of utilizing the Sun's energy and thus provide the basis for food to the entire ecosystem. For that reason, the greatest amount of biomass in the ecosystem must come from producers to be able to support higher organisms. When moving up to another trophic level, the higher levels have 1/10 of the biomass of the previous level of the pyramid.
