Nature is a wonderful recycler! A composting pile helps turn old plants and things like vegetable peelings, dead leaves and grass clippings into food and soil for new plants to grow. Compost helps plants grow because it supplies nutrients to feed plants. These nutrients were originally part of living plant tissues, but they are released when the plants are broken down. In this way, composting is an important kind of recycling. Worms and insects are an important part of composting because they help to create air pockets for air and water. Air and water in the soil benefits plant roots and creates a healthy environment for soil animals and beneficial microbes, and all of these help plants grow.
