Trophic Cascade A series of changes in the population sizes of organisms at different trophic levels in a food chain, occurring when predators at high trophic levels indirectly promote populations of organisms at low trophic levels by keeping species at intermediate trophic levels in check. Complex interactions within food webs may limit trophic cascades, and researchers have debated where trophic cascades are most likely to occur and their relative strength. First order consumers C.
