How might a lack of sunlight disrupt the food web?

A lack of sunlight may cause all or the plants to die because plants need the sun's energy to make food. When all the plants are dead, then all of the herbivores, or plant eaters, would die or migrate because they only eat plants and do not eat meat.

Producers would die, and if producers died, consumers would die too ... food chains show energy being transferred and food webs show organisms linked to each other.
