Organisms must have variation within a population in order for natural selection to occur. Which situation is an example of this variation? A frog living in a pond is eaten by a predator, while others in the same population survive. A snake living in a desert produces more offspring than other snakes in the same population. Some rabbits living in a forest have short, spotted ears, while others have long white ears. Some birds living in a grassland eat less than other birds who eat the same food.
