give reason why flow of energy is unidirectional

THE FLOW OF ENERGY IS UNIDIRECTIONAL BECAUSE;
*green plants capture 1% of energy of sunlight that falls on their leaves and convert it into food energy.
*when green plants are eaten by primary consumers a great deal of energy is lost as heat to the environment.on average 10% of food eaten is turned into its own body and made available for next level of consumers
*thus,10% can be taken as average value,the amount of organic matter present at each step and reaches the next level of consumers.
*as very less energy is available for next level of consumer food chain consists of only 3 or 4 steps.the loss of energy at each step is so great that very little energy remains after four trophic levels.
*there are a great number of individuals at lower trophic levels i.e at the producer level of ecosystem
*therefore in an ecosystem the sun's energy is transformed by producers into chemical energy by the process of photosynthesis
*in herbivores and carnivores this energy is then transformed further at various trophic levels.
*the chemical energy is transformed into mechanical energy and heat
*thus,energy flow from sun through producers to consumers is unidirectional.
