Detailed explanation-1: -These storms drive natural ecological processes like erosion, deposition, and vegetational succession which result in changed but healthy ecosystems.

Detailed explanation-2: -Natural causes of changes in ecosystems include wildfire, disease, and flooding. Human causes of changes in ecosystems include clearing land for other use, pollution, and introducing invasive species.

Detailed explanation-3: -Hurricanes can radically affect marine ecosystems, changing seafloor habitats as well as levels of oxygen, salinity, and pollution in the water. Hurricanes are tropical cyclones that produce strong winds and heavy thunderstorms.

Detailed explanation-4: -Changing temperature extremes, wildfire patterns, sea level rise, hurricanes, floods, droughts, and warming ocean temperatures have already redistributed species and modified ecosystems, and they will continue to do so.

Detailed explanation-5: -Important direct drivers include habitat change, climate change, invasive species, overexploitation, and pollution.
