because the biomass is getting smaller
Energy is lost as it moves up the energy pyramid due to inefficiencies in energy transfer, metabolism, and heat loss from organisms. In the biomass pyramid, energy is lost through respiration, growth, and waste production. In the numbers pyramid, energy is lost as it moves up due to population control mechanisms, such as predation and competition.
There are fewer organisms higher on the energy pyramid because energy is lost as it moves up the food chain through consumption and metabolism. This results in less energy available to support higher trophic levels, leading to a decrease in the number of organisms at each successive higher level.

A pyramid of energy shows the flow of energy through different trophic levels, with energy decreasing as it moves up the pyramid due to inefficiencies in energy transfer. A pyramid of biomass, on the other hand, represents the total mass of organisms at each trophic level, showcasing the amount of living material present.
The energy pyramid illustrates the flow of energy through trophic levels in an ecosystem, with energy decreasing as it moves up from producers to consumers. It demonstrates that energy is lost at each level due to metabolic processes, limiting the number of organisms that can be supported at higher trophic levels.
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.
Energy transfer can be represented by the food chain. The sun's light is acquired by plants and converted to energy by photosynthesis. Herbivores (plant eating organisms) get this energy by consuming plants. The organisms of herbivores convert the nutrients from plants into useful energy by respiration. The herbivores are consumed by other organisms, for instance carnivores and omnivores (such as humans) to provide energy for their survival.Some organisms (such as some reptiles and fish) are ectothermic and require external heat sources to survive.

The energy pyramid has a broad base to support the next level of organisms, then gets narrower as each layer is added. Each upper level eats more than one ie many organism from the layer below it. Therefore, there has to be more organisms and more energy trapped in lower layers to give energy to the upper layer. There is more grass than rabbits, there are more rabbits than hawks. There is more energy in the grass layer than the layers above it.
An energy pyramid for a small garden could display the flow of energy through different trophic levels in the ecosystem. At the base, primary producers like plants would be represented, followed by herbivores, then carnivores at the top. This visual representation would show how energy decreases as it moves up the pyramid, highlighting the interdependence of organisms in the garden ecosystem.
