How can an ecosystem change gradually?

What are some causes of sudden ecosystem changes?

A combination of climate change, fishing pressure, pollution, and nutrient run-off from land is gradually eroding the reefs’ capacity to deal with shocks and disturbances, such as storms or heatwaves – in other words reducing their resilience, and putting these ecosystems at risk of a regime shift.

What happens when an ecosystem changes?

If organisms cannot adapt to the changes in their ecosystem, they may move to another location. If they will not move, the species may become threatened, endangered or extinct. Changes to ecosystems can have tremendous effects on the organisms that live there. Sometimes organisms can adjust to these changes.
