Wraps. Zustand: Good. Presumed First Edition, First printing. iv, 64 pages. Illustrations (Figures and Tables). References. A food web (or food cycle) is the natural interconnection of food chains and a graphical representation (usually an image) of what-eats-what in an ecological community. Another name for food web is consumer-resource system. Ecologists can broadly lump all life forms into one of two categories called trophic levels: 1) the autotrophs, and 2) the heterotrophs. The food web is a simplified illustration of the various methods of feeding that links an ecosystem into a unified system of exchange. There are different kinds of feeding relations that can be roughly divided into herbivory, carnivory, scavenging and parasitism. Some of the organic matter eaten by heterotrophs, such as sugars, provides energy. Autotrophs and heterotrophs come in all sizes, from microscopic to many tonnes - from cyanobacteria to giant redwoods, and from viruses and bdellovibrio to blue whales. A simulation of the radionuclide migration through surface water bodies is presented. Compartmentalized models for both fresh water and shallow marine ecosystems are used. Transports considered include: ingestion, egestion, molting, erosion, deposition, association-disassociation, etc. These transports are parameterized in terms of a carefully selected data base taken from the literature. The application of the methodology is illustrated for consideration of a fresh water, an estuarine and a coastal ocean ecosystem. The model is presented in a form that allows ready application to other shallow water ecosystems.…
