Jerrod and his family hike on a glacier when they visit Alaska. As he hikes, Jerrod wonders how glaciers affect the surface of the Earth. Glaciers affect Earth's surface by weathering it. Explain if the weathering caused by glaciers is mechanical or chemical.

there really is life in the deepest part

sheep is a herbivore animal whereas grasshopper belongs to the class chordates but both of them feed on greens.  

if grasshopper and sheep feeding on a pasture land, i do not think both of them will have any impact on each other. however, the number of the species can make difference. since sheep feed on greens, there is a possibility there left no pasture land for the grasshoppers or they may get extinct.
