In a good pyramid there is typically less biomass at the top in three to five sentences explain the phenomenon, siting evidence relating to energy flow and how plants support ecosystems
1 answer
The phenomenon of less biomass at the top of a pyramid can be attributed to the inefficiency of energy transfer through trophic levels. As energy flows through the food chain, it is lost as heat and used for cellular respiration, limiting the amount of energy available to higher trophic levels. Additionally, plants occupy the base of the pyramid and support ecosystems by converting solar energy into chemical energy through photosynthesis. This process provides the energy necessary for all other organisms in the ecosystem to survive and grow. As a result, there is a larger amount of biomass at lower trophic levels, such as plants, compared to higher trophic levels, such as top predators.
