Hurry! organisms must have variation with a population in order for natural selection to occur. a)a frog living in a pond is eaten by a predator, while others in the same population survive. b) a snake living in a desert produces more offspring than other snakes in the same population c)some rabbits living in a forest have short, spotted ears, while others have long white ears. d) some birds living in a grassland eat less than other birds who eat the same food

I took the same quiz and got stuck on this question i got rid of A and B and then got stuck I picked the answer C because D just says they eat less which means nothing. I'm sorry if this is wrong.

To shorten it the answer is C again sorry if i'm wrong.

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.
