Actually, composting is when cuttings and organic matter from food waste and leaves, is wetted down and layered in a pile perhaps inside a bin. After months, due to bacterial action, these materials break down into humus, technically not dirt, but, it is organic material found in soil, which is made of minerals from rocks that have weathered. Bacteria convert the materials into heat, carbon dioxide and ammonium, this ammonium further breaks down by bacteria into nitrites and nitrates. These substances act as fertilizer and help plants manufacture plant proteins and grow. It is recycling at its finest because instead of throwing out yard waste, it is converted to something useful to grow more plants.

Composting is a form of recycling because it takes food and yard waste and places it in conditions conducive to breakdown of the substance.  Over time, it is broken down enough so that it becomes dirt.  The advantage of the dirt produced from this waste is that it includes all of the nutrients that were present in the food or yard waste.  Now the dirt containing those nutrients can be redistributed back on the ground (such as in a garden) and provide new plants with the nutrients they need to grow.  So the same nutrients are used repeatedly and provide the new plants with what they need to grow. 

Just like we take an aluminum can, recycle it, and reuse the aluminum in the production of another can, we can do the same thing with food and yard waste.
