What is the major disturbance that caused the ecosystem to stabilize at a new equilibrium?

A major disturbance that can cause an ecosystem to stabilize at a new equilibrium is a natural disaster, such as a wildfire, hurricane, or volcanic eruption. These events can drastically alter the landscape, destroy habitats, and shift species populations. Over time, the ecosystem may recover and adapt to these changes, leading to a new balance of species and interactions, often resulting in different biodiversity and ecosystem functions compared to the pre-disturbance state. This process is known as ecological succession, where new species may dominate and existing ones may decline or shift.
