Answer :

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.
