Answer:
B.
Step-by-step explanation:
Answer choices A, C, and D are unrelated to the food web and cannot be determined as true. For example, the food web doesn’t tell us that prairie dogs eat plants that cattle graze on (yes, both feed on grass and it is shown in the food web, but we don’t know if it is true for other plants they eat). Next, the food web doesn’t tell us that prairie dogs dig in soil and increases soil quality for plants (it could be assumed but not validated). Finally, we can’t be sure that prairie dogs make burrows that are important habitats for other species.
A food web only shows the “flow of energy”, or what eats what. Because many arrows on the prairie dog points to other animals, many animals eat prairie dogs. Thus, prairie dogs are an important food source for other species and B is the best answer.
