Food webs BT - Food Webs

Abstract

Food webs are diagrams depicting which species in a community interact. They depict binary relationships — whether species interact or not — and must miss much important biology. In the real world species interactions change at least seasonally and not all interactions are equally strong. Food webs are thus caricatures of nature. Like caricatures, though their representation of nature is distorted, there is enough truth to permit a study of some of the features they represent.
