Explanation:
Deer is a herbivorous animal that does not consume meat. In order to fulfill it's nutritional needs, they rely on plants, grass, bushes and trees.
However, these do not have a large amount of solid matter. They have a huge water content and the dry mass found in these food sources is quite low.
