Question

In which trophic level carnivores present in energy pyramid?

Answer 1

They occupy 3rd trophic level.

More specifically...,
Primary carnivores occupy 3rd trophic level and secondary carnivores occupy 4th trophic level

Answer 2

A pyramid of energy represents how much energy, initially from the sun, is retained or stored in the form of new biomass at each trophic level in an ecosystem. Typically, about 10% of the energy is transferred from one trophic level to the next, thus preventing a large number of trophic levels.
