Scientists have long been mystified about how animals who munch on plants in Yellowstone National Park all get enough food to eat.
Animals all living in the same habitat and eating the same foods manage to co-exist thanks to slight differences in feeding habits—based on their body size, according to a new paper in the journal Royal Society Open Science.
This allows all these herbivores to live alongside each other and still find enough plants to eat.
