Our star, the sun, has a temperature of 5,530 degrees Celsius and has a luminosity of 1 solar luminosity units. At which letter on the HR Diagram would you place our sun?

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.
