What would happen if an organism was removed from the food web?
If the sun was removed from the food web, then every organism would die. The sun is a source of energy for the plants. Without the sun, the plants have no way to make their food, so they would die. If the plants died, then the herbivorous animals would leave in search of food or die. Without herbivorous animals to eat, the carnivorous animals would leave in search of food or die, too. Therefore, if the sun was removed from the food web, every organism would die.
