Plants take up carbon dioxide from the air and nutrients from the soil. this is an example of interactions between the

geosphere, cryosphere, and atmosphere

biosphere, atmosphere, and geosphere

atmosphere, hydrosphere, and geosphere

cryosphere, atmosphere, and hydrosphere

the correct answer is:

a population changes in response to a change in the environment.

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.
