During the nineteenth century, biologists knew that South America and Africa contained similar fossils. These fossils led them to believe that a temporary land
bridge between South America and Africa allowed ancient species to move between
both continents. In the twentieth century, evidence showed that South America and
Africa were once part of the same larger continent and that there were no land bridges
between them. How should biologists respond to the new geological finding?

hello which   of the following there is nothing!

who knows

explanation:

true is the answer : )

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.
