•There are two main reasons why food goes off: oxidation and bacterial action.
•Oxidation is the action of oxygen on just about anything and is what causes food to go 'stale'. Think Sandwiches on a plate for a couple of hours. The best way to prevent this happening is to wrap the food or keep it in an air-tight container.
•Bacteria is all around us. There are trillions of bacteria in your kitchen right now. Of course you can't see them and the vast majority are completely harmless, some are even beneficial, but there are a few that are quite nasty indeed. Bacteria cause food to go bad and some can even lead to food poisoning.
•Bacteria feeds off the food and produces waste which is poisonous to us. That is why things in cans for instance, take a long time to go off, because no bacteria can get to it.

A food chain is made up of primary producers (organisms that make their own food, ex. plants), primary consumer (organisms that eats a primary consumer better known as called a herbivore) and a secondary consumer (organisms that eat primary consumer). But sometimes the food chain go on for longer.
