In a particular food chain, if the energy produced by the autotrophs is 1000 Kcal, then the amount of energy which reaches fourth trophic level is:

Sustainable Vegan - The higher one goes on the food chain, larger is the loss of energy. So, why not get it from the source? Eat plants, live long & keep calm!
