For example, insects and other arthropods contribute substantially to standing biomass; 1,000 kg/ha is an estimate for the United States (Pimentel . 1980). In most terrestrial and freshwater ecosystems they play critical roles as prey, predators, herbivores and pollinators (Free 1970; Debach and Ros
