Food webs

It shows what the living organisms eat and what eats them.
A food web consists of many overlapping food chains.
Food webs can be quite complicated.
I think food webs show more infromation then food chains but they can be hard to follow somtimes.
Two pieces of information that I learned from another site are:
1. a drought can cause animals to become endangered
2. pollution can cause a break in a food web
