An EF5 tornado is the strongest type of tornado and has wind speeds over 200 mph. What type of impact would this have on an
ecosystem?

An EF5 tornado is a devastating tornado in which the wind speed is usually in between 250 mph to 320 mph.

Such high speed tornadoes might completely eradicate an ecosystem. Even the strongest of trees break as a result of such devastating tornadoes.

The organisms present in the particular ecosystem where such high-intensity tornado has occurred will not have enough food and will also lack shelter. Some of the organisms would die due to lack of resources, others will try migrating to different places. In this way, the whole ecosystem will be disrupted.
