Which is true of animals?

a. they eat dead or living organisms.

b. they have coordinated movement.

c. they develop a blastula.

d. they make their own food.

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.

thats not even an aswer choice
