Question

Elk herds in Yellowstone National Park are herbivores that eat on the available vegetation. Which factor is important to ensure the stability of this ecosystem?

Answer 1

Predators, like wolves, to eat the elk so that the vegetation won’t be demolished

Answer 2

The presence of predators

Step-by-step explanation:

What will happen without the presence of predators in this ecosystem is that the herd without a natural predator will turn into an uncontrollable plague to the environment and will end up destroying all the environment in which they live which will cause a lack of natural resources and consequently expel other species for lack of food and water, making in the near future impossible the life of other species in that environment and in time even the herd will be forced to flee from that place.
