Use the image below to answer the question.
The plants are eaten by consumers at the first level, such as a mouse, grasshopper, whiptail, frog, squirrel, and deer. The consumers at the second level, such as ringtail, eagle, and pine marten eat the consumers at the first level. The consumers at the third level, such as wolf, mountain lion, and bobcat eat the consumers at the second level. Some of the consumers at the first level are also eaten by consumers at the third level.
Of the predators in the image, which one is most likely a keystone species?
