All the options listed can cause significant disturbances to ecosystems, but if we are to identify one that is typically considered an extreme disturbance, **hurricanes** would be the most fitting choice. Hurricanes can cause widespread destruction, altering landscapes and disrupting the balance of ecosystems significantly.

The correct response is **living things in that ecosystem.**

Disturbances such as fire or toxic chemicals can impact all the living organisms within the ecosystem, including plants, animals, and microorganisms, as well as their interactions and the overall health of the ecosystem.

The correct response is **The plant population would decrease.**

If the deer population increases, they will consume more grass and other plants, leading to a decrease in the plant population. This could ultimately impact the entire ecosystem, including the lions, as their prey (deer) may eventually be affected by the reduced plant availability.

The correct response is **the loss of a river system due to contamination.**

This represents a severe disruption to an ecosystem because it can have long-lasting effects on water quality, aquatic life, and the overall health of the ecosystem, impacting not only the organisms that live in the river but also those that rely on it for survival.
Answered by GPT-4o mini
The correct response is **die out in the area.**

If an ecosystem is irreversibly destroyed and species are unable to travel or adapt to the new conditions, they will not be able to survive, leading to their extinction in that area.
