Answer:
almost 20 years ago (used extinguished 70) until in the end, change after change, this has meant a change in the channel of the rivers. Already in the middle of last year the news of the increase in the number of grizzly bears in the park came out, due to an increase in bushes and fruits, which feed the bears, caused by a decrease in elk. This effect is due to the phenomenon known as waterfall or trophic network. A trophic cascade is the succession of elements that serve as food for others in an ecosystem. Let's see it in a simple way: there are producers who contribute organic matter (such as vegetables and some microorganisms), primary consumers (who feed on producers; they are herbivores), secondary consumers (who feed on primary ones) and tertiary consumers or super-predators (who feed on the secondary ones, or on any other link in the food chain). There are also decomposers, which are fungi.
Explanation:
In the case of Yellowstone, the wolf is a super predator and its absence led to an excess increase in the lower links, such as that of the elk. The moose wiped out the vegetation and this meant that the number of many animals that live in or feed on trees and shrubs, such as the bear, disappeared or decreased. In turn, as the number of prey decreased, the number of birds of prey and scavengers also fell. Currently, the presence of the wolf has restored all the balances: the number of moose has decreased and the vegetation has increased, bears, small mammals, birds of prey and scavengers, other scavengers such as foxes or weasels ... being the only victim. the coyote. That which is said that "nature is wise" is a truth like a temple. Ecosystems know how to regulate themselves without needing to receive extra “help”. In other words, the excuse of the hunters that they kill to regulate the life of the mountains is nothing more than that, an excuse to kill. Here we should take good note of this and stop the wolf slaughter that is taking place in Asturias and Castilla y León (we tell you here). The Yellowstone case is an example that could not be more clear. And, so that you have no doubts about the process that occurred, I leave you the Sustainable Man video, with subtitles in Spanish. A video that has no waste, not a single one of the 4 minutes it lasts.
