Answer 2

All of the options listed can be considered extreme disturbances to ecosystems, but if you need to choose one that is often highlighted for its severe impact, **coral bleaching** is frequently cited due to its widespread effects on marine ecosystems. Coral bleaching occurs when corals lose their symbiotic algae (zooxanthellae) in response to stressors such as elevated water temperatures, leading to large-scale damage to coral reefs and the diverse marine life that depends on them.

If you are looking for a general consensus on extreme disturbances, **extreme temperature change** could also be considered because it can affect numerous ecosystems simultaneously. However, the severity of impact can vary by context, so depending on specifics, the answer might differ.

Ultimately, the answer could also depend on the context of your study or interest.
