EXPLORING TROPHIC CASCADES Ecosystems are composed of a community of organisms and their physical environment. Ecologists study the interactions among these organisms and the factors that affect organisms' distribution. The structure of the ecosystem can be represented by a pyramid made up of trophic levels, in which producers are on the bottom, followed by primary consumer, secondary ...Oct 6, 1999 · These early studies were the inspiration for hundreds of investigations on other keystone species and trophic cascades, as well as ongoing studies into the regulation of population sizes and species numbers.
