WebNov 1, 2000 · Trophic cascades are the time-honored focal point of food-web dynamics. They are the best loved example of indirect effects in undergraduate ecology textbooks and they represent a potentially useful application of theory. Researchers have found them from the Arctic to the tropics. But, can we agree on what they are? WebAn organism that consumes another organism for food. Food chain. A series of organisms in which energy is transferred to another. Food web. A network of feeding interactions, usually consisting of multiple food chains. Trophic level. Each step in a food chain or food web. Biomass. The total amount of living tissue within a trophic level.
