Energy flow in an ecosystem is unidirectional. Energy flow in ecosystems The way energy passes through an ecosystem is described as energy flow. No transfer of energy is 100 per cent. To show the flow of energy through ecosystems, food chains are sometimes drawn as energy pyramids. These levels are used to describe ecosystem structure and dynamics. The flow of energy in the ecosystem is unidirectional because the energy lost as heat from the living organisms of a food chain cannot be reused by plants in photosynthesis. It means that energy which is absorbed by the producers from sun and is converted into chemical energy, always flow from a lower trophic level to a higher trophic level as in a food chain when herbivore consumes producers the energy is transferred from producers to consumers and so on. The process ends when the carnivores die and get decomposed, thereby becoming food for plants and starting the cycle again.
