What are examples of macrorganisms in a compost pile?

Among the most helpful macroorganisms in a compost pile are ground beetles and worms. For they help break down the compostable materials, such as grass clippings and other yard wastes, and kitchen scraps. They also feed on other ground-dwelling organisms that may wander into the pile, die and decay. The consequence is the decomposition of compostable materials into dark brown, organic matter-rich compost that encourages healthy plant growth and healthy soil structure. For the breakdown adds to the amount and range of the 16-17 nutrients that are necessary to plant and soil health. Among those nutrients is nitrogen, which may be found within the soil, or within organisms, but needs the release of digestion and elimination in order to be available to plant roots.
