Answer the following:

Construct a simple food chain.

Grass → Grass hopper → Frog → Snake → Eagle

A Food chain shows the relationship between plants and animals wherein food energy gets transferred from one trophic level to the another. Grass (plants) are the producers, grass hoppers act as the primary consumers which feed on grass and are in turn eaten by Frog that is secondary consumers. Snake, the tertiary consumers feed on frogs and are in turn eaten by Eagle which is a quaternary consumer.
