Asexual reproduction occurs during which of the following processes?

Mitosis.

Explanation:

Hey! Asexual Reproduction requires 1 parent only meaning only 1 parent makes offsprings to their children. Since all offspring have the same DNA as the parent, it requires mitosis to make 2 cells a single cell. I hope this helped!

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.
