If all the plants on earth died, eventually on the living beings on the planet will also die. Human beings and other animals need plants to live. When green plants make food, they give off oxygen. This is a gas that all animals need to breathe in order to stay alive. Without plants, animals would have no oxygen to breathe and would die. Animals also depend on plants for food. All animals eat either plants or plant-eating animals. Without plants, there would be no food to eat. So, both the options are correct, but the immediate consequence of the absence of plants would lack of oxygen. If there is no oxygen, there would be no photosynthesis and hence, no food.
