A food web is similar to a food chain but larger,and it is a diagram that combines many food chains into one picture.
For example, a tree produces acorns - this is called the producer. Mice, squirrels, and insects eat these acorns and because there are many mice, the weasels, snakes and raccoons have food. With insects in the acorns, other predators would be attracted (like skunks or opossums) and therefore, foxes, hawks or owls could all find food. y bigger Food webs can be effected in many ways considering the urban areas of major countries are taking no action and care.it uses arrows to show the energy relationships among organisms
