Explain energy pyramid
Advertisements
उत्तर
Pyramid of energy is always upright, it can never be inverted. When energy flows from a particular trophic level to the next, some energy is lost as heat at every step. There is the unidirectional flow of energy. The energy captured by autotrophs does not go back to the solar input or the energy which passes to herbivores does not go back to autotrophs. As the energy flows progressively through various trophic levels it is no longer available to the previous trophic level
