Question

Not all energy an organism takes in it transferred to the next organism because

Answer 1

the organisms uses most of the energy it takes in to sustain their own life

Answer 2

In an ecosystem energy flows in one direction, that is from producers such as green plants to plant eaters or herbivores to carnivores and decomposers. During energy transfer, some of the energy is used for the growth and development of the organism and large amount of energy is lost into the environment as heat. Thus. According to energy transfer law, only 10 % of the available energy is transferred to next trophic level to support life.
