Nahrungsnetz

Netzartiger Verbund von Nahrungsbeziehungen. Nur wenige Tiere ernähren sich nur von einer Pflanzen- bzw. Tierart bzw. haben nur einen Feind. Daher verzweigen sich Nahrungsketten zu komplizierten Nahrungsnetzen. Im Idealfall werden auch Symbiose und Parasitismus berücksichtigt. Nahrungsnetze können bisher nur für kleine, abgegrenzte Ökosysteme (z.B. kleiner See) erstellt werden.
