Final answer:
Grasshoppers jump using powerful hind legs with large muscles and an exoskeleton for support.
Step-by-step explanation:
The question "explain how jumping occurs in grasshopper" relates to biology, specifically to the anatomy and locomotion of insects. Grasshoppers jump using their powerful hind legs, which have large muscles that contract and release to produce a rapid extension of the leg. This action launches the grasshopper into the air. The grasshopper's exoskeleton provides structural support for muscle attachment, while its legs are adapted for jumping, with long femurs and elongated tibia that act as levers.
