The secondary consumers would have no food either. Spiders would die for lack of food, causing the shrews to also go hungry. You can imagine how that would affect the weasel, the red-tailed hawk and the great-horned owl. The scavengers and decomposers would be the only ones who would feast!!! But just for a short time – after that there might not be any animals left at all. A food web protects the balance of food and consumers by spreading the food sources and the eaters around.
