Quick! i need to know: in the stage 2 of photosynthesis, nadp+ becomes nadph by adding an h+. where does the h+ come from

the H+ comes from the splitting of water

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.
