Gorillas live in the rain forest, just like all other great apes. Only chimpanzees occur in the african tree-savannah as well. Everyday the Gorillas wander around in their areas, from one feeding ground to another. They feed almost exclusively on plants, which they consume in large volumes. Without forests Gorillas cannot survive. They only leave the forest when they are searching for food in the open grassland.
