A biologist is studying the genetics of a particular species of plant. He knows that one plant may contain hundreds of individual seeds, each of which is the result of a separate fertilization event. He determines that seed shape is controlled by a single gene with two alleles. The dominant allele results in round seeds, and the recessive allele results in wrinkled seeds

b.have there own function.

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.
