In an ecological pyramid, what happens to energy, number of organisms & biomass as you move up in the environment? Why?

They all decrease because energy is lost as it moves up each trophic level. Each trophic level requires more energy to sustain it, increasing competition for resources and causing number of organisms to drop. What is biomass?

Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level. Trophic level transfer efficiency (TLTE) measures the amount of energy that is transferred between trophic levels.
