    Well to make a food web you first got to know what gives energy to what. Say you start with grass. What does grass give energy to? well, maybe a deer? so you should draw an arrow from the grass pointing to the deer. Another example is with a tree. What do trees give energy to? Trees give energy to seed-eating birds. So you draw the arrow from the tree point to the bird. Do you get what I am saying?
