What is meant by trophic levels?

1 Answer

A trophic level is a stage in the food chain.


Food chains start with a primary producer that fixes energy.

The energy is then transferred to the next trophic level, herbivores.

These herbivores (the primary consumers) are eaten by the organisms in the next trophic level (secondary consumers) and the energy is transferred.

The process continues till the end of the food chain which rarely exceeds five trophic levels.
