Describe the difference plate boundaries?

There are four types of plate boundaries:  

Divergent boundaries -- where new crust is generated as the plates pull away from each other.  

Convergent boundaries -- where crust is destroyed as one plate dives under another.  

Transform boundaries -- where crust is neither produced nor destroyed as the plates slide horizontally past each other.  

Plate boundary zones -- broad belts in which boundaries are not well defined and the effects of plate interaction are unclear.

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.
