Question

Depict a food chain by placing the following organisms in the correct order by their trophic levels.
Grass, Grasshopper, Frog, Snake, Eagle:

Answer 1

The food chain is the sequence of organisms through which food and energy pass in an ecosystem with the members of each trophic level. The grass is the producer on which grasshopper is dependent and thus is the primary consumer, frog feeds on grasshopper and snake feed on frog whereas eagle is at the apex of the trophic level and derives its nutrients from the snake. Thus the food chain is depicted as

$Grass\to grasshopper\to frog\to snake\to eagle$.
