I always wondered this. I guess zombies don't require all the metabolic processes that we do (breathing, skin cell replacement, pumping blood, etc), so they can just lie down and literally expend zero energy. That way they can lie around forever waiting for someone to happen by.
Even expending 0 energy wouldn't prevent organic material from decomposing. After an animal dies, the corpse just sits there doing nothing and falls apart on its own.

Could they not be feeding on eachother? Animals? Rats. Etc
They definitely can't eat each other. The ones that are walking around open spaces freely can be feeding on animals, but I'm talking about the ones that are confined in a space. For example, take the incident when Shane and Rick were fighting and Shane threw that big tool at Rick, broke a window then the zombies started pouring out of the building through that window. They couldn't have gotten enough food in that space to keep their cells intact for more than a week.
