Trophic Levels : The various steps in a food chain at which the transfer of food (or energy) takes place are called trophic levels.
Example : A food chain operating in a grassland is given below :
Grass → Insects → Frog → Birds
In this food chain
- Grass represents first trophic level.
- Grasshopper represents second trophic level.
- Frog represents third trophic level.
- Eagle represents fourth tropic level.
