"Organic" refers to the way farmers grow and process their produce. Fruits, vegetables, dairy products, and meat are often grown and processed this way. These are often more expensive than inorganic products and spoil easily. Unlike conventional or inorganic farmers, organic farmers use natural fertilizers and methods to reduce pests and diseases. Organic farmers do not give antibiotics or growth hormones to animals like conventional farmers. In addition, organic farmers do not use medication to prevent diseases in animals. While conventional farmers give limited space to their animals indoors, organic farmers allow their animals to access the outdoors.
