english: A trophic cascade is an ecological process which starts at the top of the food chain and tumbles all the way down to the bottom, and the classic example is what happened in the Yellowstone National Park in the United States when wolves were reintroduced in 1995.
non_english: Trofska kaskada je ekološki proces koji počinje na vrhu lanca ishrane i pada sve do dna, i klasični primer toga je nešto što se desilo u Nacionalnom parku Jeloustoun u Sjedinjenim Državama kada su vukovi vraćeni 1995. godine.
