Question

Environmental factors can have various effects on ecosystems. In August 2005, Hurricane Katrina caused significant damage in several states along the Gulf Coast, including Alabama, Mississippi, and Louisiana. Thousands of people were evacuated from their homes due to flooding and other damage caused by the storm. What environmental impact would Hurricane Katrina not have caused?

early onset of spring
change in marine ecosystems
change in animal migration
change in habitats

Answer 1

Early onset of spring.

Hurricanes cause physical damage — altering marine ecosystems (storm surge, salinity, pollution), disrupting animal movements, and destroying or changing habitats — but they do not trigger a seasonal shift like an early spring.
