Question

Why energy flow ecosystem in one way

Answer 1

energy flow occurs in a food chain in one way since the prey cant feed on its predators.

the energy transferred at each trophic level is 10% of the previous level due to utilisation of energy as heat

only 10% of the food we eat is transformed into our own body and the energy is made available to next trophic level

since the energy consumption is so high at each trophic level,the chemical energy provided by plants is exhausted after 4 or 5 trophic levels

there is no phenomenon in earth to transform chemical energy into solar energy

the main is that  food chain cant be reversed ie, deer cant feed on lion

ie prey cant feed on predator.ie noe energy is transferred from lion to deer.but energy is transfered fro deer to lion
