Earthworm crawling on soil in a compost pile in Issaquah, Washington, USA. Worms play an important part in soil construction and recycling of organic waste. They are a part of a network of organisms that turn refuse into nutrient rich soil. These nutrients are one of the benefits of garden worms to plant growth. Worms in gardens also perform cultivation functions that increase soil porosity and allow oxygen in to roots.
