In a food pyramid there is typically less biomass at the top in three to five sentences explain this phenomenon citing evidence relating to energy flow and how plants support ecosystems Short sentences

In a food pyramid, there is less biomass at the top because energy is lost at each trophic level as it moves up the pyramid. Plants support ecosystems by converting sunlight into energy through photosynthesis, which is then transferred to herbivores when they consume plants. However, not all of the energy from the plants is transferred to the herbivores, as some is expended in metabolic processes or lost as heat. This energy loss continues as you move up the trophic levels, resulting in less biomass at the top of the food pyramid.

In a food pyramid, less biomass at the top is due to energy loss as it moves up trophic levels. Plants support ecosystems by converting sunlight into energy, but not all of this energy is transferred to herbivores. Energy is lost in metabolic processes and as heat, leading to a decrease in biomass at higher trophic levels.
