A farmer is analyzing cross sections of his land to determine where to build a well.

Which phrase describes the best area to dig down to the groundwater?

{r]{y}     {r]{y}

{y}{r .     {r}{y}

explanation:

amber has allowed scientists to study dna that has been preserved over millions of years.

x would be the most and the least would be y because there are more fruit   and seeds than flock z has insects

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.
