      Not saying plant cells feed directly on living organisms at all. But here's
      the position of the Food & Agriculture Organization at the U.N. This is as
      strong an argument against chemicals and for organics as can be found

      Organic matter, microbes, and plant health

      "Soil organisms contribute a wide range of essential services to the
      functioning of all ecosystems. They act as the primary driving agents of:
      nutrient cycling, regulating the dynamics of soil organic matter, soil
      sequestration and greenhouse gas emissions; modifying soil physical
      and water regimes; enhancing the amount and efficiency of nutrient
      by the vegetation; and enhancing plant health. These services are not only
      critical to the functioning of natural ecosystems but constitute an
      resource for sustainable agricultural systems."

      "Each type of soil organism occupies a different niche in the web of life
      favours a different substrate and nutrient source. Most soil organisms rely
      organic matter for food; thus a rich supply and varied source of organic
      will generally support a wider variety of organisms."

      "Building of soil fertility is the cornerstone of organic agriculture.
      practices create suitable conditions for soil biotic and abiotic resources
      through: manipulation of crop rotations and strip-cropping; green manuring
      organic fertilization (animal manure, compost, crop residues); minimum
      and avoidance of pesticides and herbicides use. Scientific research in
      has demonstrated that organically-managed soils significantly increase
      biological activity and total density and diversity of soil
      Such biodiversity enhances nutrients recycling and soil structure."
