Suppose a bolt of lightning starts a fire in a forest. the fire sweeps through the forest and burns away accumulations of brush and deadwood. what is the most likely effect of the fire on the forest community?

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.
