Ecosystem Cascade

Definition

An ecosystem cascade refers to a series of events that occur within an ecosystem when one change triggers a chain reaction affecting multiple other components. These cascades can have significant impacts on the structure and function of ecosystems.

Analogy

Think of an intricate domino setup where knocking down one domino causes a chain reaction that knocks down many others. An ecosystem cascade is similar, where one change in an ecosystem sets off a series of interconnected effects throughout the entire system.
