Trophic cascades have been described in numerous ecosystems, ranging from kelp forests of the Pacific Ocean, to arctic islands, to Central American jungles, to salt marshes. These early studies were the inspiration for hundreds of subsequent investigations on how population sizes are regulated in a wide variety of ecosystems. They use, rearrange, and ultimately decompose the complex organic materials built up by the autotrophs. The ecological species interactions keep entire ecosystems balanced.

Biomass is simply the amount of matter that's stored in the bodies of a group of organisms. Specifically, a trophic cascade refers to a predator's impact "trickling down one more feeding level to affect the density and/or behavior of the prey's prey" (Silliman and Angelini 2012). display: inline-block; Predation is used here to include all "+/-" interactions in which one organism consumes all or part of another. -moz-user-select:none; Predators are often particularly vulnerable to environmental stress, thus .
