Why did the removal of wolves affect the entire yellowstone ecosystem?

The wolves are the keystone species of the Yellowstone ecosystem. They prey on other organism, hence, maintain a balance in the forest. in case, the wolves are removed, the animals, which are the prey of the wolves would increase, which may lead to increase in competition and exploitation of the resources and eventually an unbalanced ecosystem.  Hence, the wolves are very important to Yellowstone.

succession returns a disturbed

ecosystem to a more stable state. this is also classified into two (2) types:

primary succession and secondary succession. the primary succession arises when

a new land is transformed and a bare rock has been exposed providing an environment

that can be occupied for the first time. while, secondary succession occurs

when a previously occupied environment was disturbed that kills much of all its

community
