Dr. Sanyang: Food Chain

The meaning of food chain is how different types of living things have to eat other living things in order to survive. for example humans eat some chicken and meat because that's what they do.
my food comes from industrial organic.

The difference between food chains is that they have different ways of being raised. For example industrial has one crop while local sustainable has many crops.
