Botany - Ecosystem Question with Solution | TestHub

The pyramid of energy is always upright because the flow of energy is unidirectional from producer to consumer level. The energy content is maximum in producers. The energy decreases at each trophic level of the food chain, as part of the energy is lost as heat, and the major part of the energy is liberated during respiration for use in various activities. Only 10% of the energy of the previous trophic level is received by the next trophic level, as proposed by 10 percent law of Lindeman (1942).
