Description	Ecological studies of direct and indirect interactions in food webs usually represent systems as unique configurations such as keystone predation, exploitative competition, trophic cascades, or intraguild predation. Food web dynamics are then studied using model systems that are unique to the particular configuration. In an endeavor to develop a more unified theory of food web structure and function, we explore here model systems in which a consumer species forages adaptively on two resource species along a gradient of environmental productivity and predation mortality. We explore the nature of trophic interactions under three different assumptions about what constitutes a resource and the spatial distribution of resources. We first examine a consumer (herbivore) feeding on two resources (plants)that are distributed randomly in the environment. We extend this to the case in which each plant resource occurs in a discrete patch. Finally, we examine a variant of the patch selection case in which the cons Ecological studies of direct and indirect interactions in food webs usually represent systems as unique configurations such as keystone predation, exploitative competition, trophic cascades, or intraguild predation.
