First of all, we need to understand that an arrow pointing at another animal means that the animal consumes it. For example, the arrow coming from carrot that points at the rabbit means that the rabbit consumes it.
73. Knowing the above, we can see that the chipmunk only has one arrow pointing at it: grains. This means that the chipmunk is the animal in the food web that relies on one source of food.
74. The two things that the cricket consumes, indicated by the arrows pointing at is, are grasses and grains. Grasses also points at rabbits, and grains also points at chipmunks and birds. Therefore, you can choose any two of the three options that also consume the grasshopper’s food: chipmunks, birds, or rabbits.
75. Carnivores are animals that eat other animals, while herbivores are animals that eat plants. The only two animals in this food web who consume other animals is the hawk and the wolf, as shown by how the arrows pointing at them are all other animals, indicating that they consume meat. Therefore, the carnivores in this food web are the wolf and the hawk.
