Two species of flies, Drosophila melanogaster and Drosophila simulans, can mate. They usually do not mate, however, even if
they are kept together in a laboratory. Males court the females of both species, but the females prefer to mate with males of
their own species. Which isolating mechanism does this describe?
behavioral
temporal
artificial
anatomical

you dont brother god luck

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.

is it multiple choice?
