Why can't plants and animals not leave what alone? Or do you mean why can humans leave them alone? Because the answer to that question is, "no one knows".

Plants make habitat for animals because with out plants animals wont have any thing to eat, both herbivores and carnivores. With out plants herbivores cant eat the plants or have enough oxygen and if there is no plants there is no rain and water. Tis also effects the carnivores since they wont have shelter or food since the cannot eat without any other animals. And they cant camouflage
Because plants don't have a need for animals, but animals need company and a mate so that they can continue and make their species last.
well on plants they die and shrivel up like a rasin. then on animals they just cant breathe.
