Write one food chain that include the marsh grass

The correct answer will be

Marsh grass→ grasshoppers→shrew→marsh hawk.

Explanation:

The food chain is a series of steps of energy transfer in an ecosystem by eating the organism and itself being eaten.

The food chain starts from the autotrophs or producers which can synthesize the food on their own like plants, eaten by primary consumers or herbivores which feeds on autotrophs. The primary consumers itself are eaten by the secondary consumers also known as carnivores and so on. The energy is transferred in the food chain via a 10% energy rule.

The food chain in marsh starts from the Marsh grass which is eaten by the grasshoppers. These grasshoppers are eaten by the shrew which is eaten by the marsh hawk.

Thus, Marsh grass→ grasshoppers→shrew→marsh hawk is the correct answer.
