The food chain of the mountain gorilla is fairly straightforward and simple. The mountain gorilla is an herbivore, meaning it eats only plants. Typically, a mountain gorilla will eat wild berries or grass. Foliage makes up the largest part of a mountain gorilla?s diet as it is plentiful, unlike sparse patches of fruits. A mountain gorilla will then, unfortunately, be hunted by humans, so poachers would be above the mountain gorilla in their food chain.
