Since we started producing nuclear power in 1960, how common are large nuclear accidents (those that resulted in the major release of radioactive material into the environment)?

six grader is what i am ssorry

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.
