Flow of energy is unidirectional in food chain ?

Due to 10% law, the energy trapped by plants from sun cannot be reverted back. Also the energy flown from producers to primary consumers followed by secondary and tertiary consumers can't be reversed. So it is concluded that energy flow is unidirectional.

Hope it will help you

tushargarg36975: When energy transfer from one trophic level to another some energy is lost in the environment in the form of heat which can't be reuse by plants for photosynthesis. So flow of energy is unidirectional in a food chain.

ay3633978: this is also correct

tushargarg36975: Yes but it is in easy language

ay3633978: I have commented for your answer only that yours is also correct and it is in easy language but is it will be asked in five marker so we can write it in detail also.

tushargarg36975: Yes I am not saying that your answer in incorrect. Your answer is very good

ay3633978: Thanks a lot

tushargarg36975: Welcome

The flow of energy is unidirectional because once the energy is lost in environment it cannot revert back to autotrophs.

Plants take 1% of energy from sun. they use this energy in making food.Now this energy will not be revert back to sun.

When these plants are eaten by consumers a great deal of energy is lost in the environment . Some energy is used up by consumers in their various life processes like breathing ,digestion, excretion etc.An average of 10% energy is left inside their body which is made available for next level of consumer.

Hence the energy captured by plants from sun and by consumers from plants cannot revert back to them , so we can say that flow of energy is unidirectional.
