This is a biotic limiting factor because it helps control population. Like if it was not there it would take away many homes and lots of food so there would be less animals, but if there was another one more animals would come and live there. It also controls what plants can grow under it by limiting the amount of sunlight the plant under it can get, also its long roots take water so the plants can't get it. If it wasn't there though more plants would grow.
