Assertion : The number of trophic levels in the grazing food chain is restricted. Reason : Energy decreases when it get transferred from lower trophic level to the higher trophic level.
In a particular food chain, if the energy produced at first trophic level is 1000 kcal, then the amount of energy which reaches fourth trophic level is .
