Foxes Owls Birds Grasshoppers Grains Mice Grasses Carrots Rabbits (Not drawn to scale) Which three organisms in the food web obtain energy directly or indirectly from grasshoppers? A. owls, birds, and mice B. owls, birds, and grains C. foxes, rabbits, and mice D. foxes, owls, and birds A bacterial disease has destroyed most of the farm’s carrot crop for the past two seasons. As a result, the rabbit population has been forced to rely more heavily on grasses for a food source. Explain how this disruption is likely to affect the rest of the ecosystem’s food web. Include multiple pieces of evidence and discuss specific populations (other than carrots and rabbits) as examples to support your answer.
