Each step or level of the food chain is known as a trophic level. Transfer of energy in the form of food takes place from one trophic level to the next.

Trophic levels can be broadly classified as Producers; Primary, Secondary and Tertiary Consumers.

An example of a food chain:

Grass \rightarrow Grasshopper \rightarrow Frog \rightarrow Snake \rightarrow Eagle 

Here, Grass is a producer, Grasshopper is herbivore, Frog is first carnivore, Snake is second carnivore and Eagle at the top is third carnivore.
