Where is the greatest amount of energy stored in an energy pyramid?

The greatest amount of energy in an energy pyramid is stored at the base, where primary producers, such as plants and phytoplankton, are located. These organisms capture solar energy through photosynthesis, converting it into chemical energy. As energy moves up the pyramid to herbivores and then to carnivores, a significant amount is lost at each trophic level primarily due to metabolic processes and heat, resulting in less energy being available to higher levels. Consequently, the energy decreases as one moves up the pyramid.
