How wolves change rivers
Hi im mannat i'm talkin about how wolves change rivers. A trophic cascade is an ecological process which starts at the top of the food chain and tumbles all the way to the bottom. And the classic example is what happened in the yellow stone national park in the united states. When wolves were reintroduced in 1995. Now we all know that wolves kill various species of animals but perhaps we are all slightly less aware that they give life to many others. Before wolves have turned up they had been gone for 70 years but as soon as the wolves came back the numbers of deer went down and there was only a few left. And it had a remarkable effects, similarly by driving the deer out of some places and the vegetation recovering on the valley sides. There was less soil erosion because the vegetation stabilized and that as well. Thank you
