Question

which is an extreme disturbance to any ecosystem?
a hurricanes
b extreme temperature change
c coral bleaching
d elk overgrazing

Answer 1

All the options listed can be disturbances to an ecosystem, but if we're looking for an extreme disturbance, the most appropriate answer would likely be **a) hurricanes**. Hurricanes are large, powerful storms that can cause significant and widespread damage to ecosystems, affecting both terrestrial and aquatic environments. They can lead to destruction of habitats, loss of species, and alterations in community dynamics.

Extreme temperature changes and coral bleaching also significantly impact ecosystems, but hurricanes tend to have more immediate and severe effects over a wide area. Elk overgrazing can lead to localized disturbances but may not be considered as extreme as the others in a broader ecological context.
