Which of the following is not part of the water cycle?
a) fixation
b) precipitation
c) condensation
d) evaporation

i think it is a but i'm not sure. i don't remember going over this in class

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.
