Answer

Answer:

the loss of any one species in an ecosystem

Brief Explanations:

A trophic cascade is often triggered by the removal of a key - species (which can be a top - predator or a keystone species). The loss of any species can disrupt the food web and cause a cascading effect on other species in the ecosystem. No change in factors won't cause a trophic cascade, and the gain of a new species may not always lead to a trophic cascade as compared to species loss.
