Expert Answer:

It will be difficult understand the concept if we consider a single food chain.

In a food web, an organism can occupy different trophic levels in different food chains. This means an organism can eat different preys. For example: A carnivore such as tiger may eat rabbit in one food chain or a deer in another food chain. Depending upon the biomass of the prey, the amount of energy obtained will definitely vary. It is very uncertain to say that organisms at higher level always eat more number of preys. These organisms may or may not eat more number of preys since the consumption of different prey provide them varied amount of energy.
