The mouth parts of a grasshopper are adapted for

The grasshopper is a herbivorous insect that feeds on leaves, grasses, and other plant material. Its mouthparts are of the biting and chewing type, which is the most basic and generalised form of insect mouthpart.

The key structures of a grasshopper's mouthparts are:

• Labrum (upper lip): a flap that holds food against the mandibles.
• Mandibles: a pair of hard, strong, toothed jaws that move sideways to bite off and crush pieces of plant material.
• Maxillae: a pair of accessory jaws behind the mandibles that help manipulate and further chew the food.
• Labium (lower lip): holds the food in place during chewing.
• Hypopharynx: a tongue-like structure that helps move food into the oesophagus.

Piercing and sucking mouthparts are found in insects such as mosquitoes and aphids, which feed on fluids (blood or plant sap). Sucking mouthparts (without piercing) are found in butterflies and moths, which use a coiled proboscis to drink nectar. The grasshopper does not suck fluids; it physically bites off and grinds solid plant tissue.

The correct answer is biting and chewing.
