Question

25 multiple choice 1 point the gulf dead zone shows how: the midwest is not connected to the gulf pollution stays only in local rivers farming in one region affects ecosystems far away hurricanes are the main cause of fish death

Explanation:

The Gulf dead zone is caused by nutrient pollution (like from agricultural runoff in the Midwest) that flows down rivers to the Gulf, creating hypoxia. Option A is wrong as the Midwest is connected via rivers. Option B is wrong as pollution moves beyond local rivers. Option D is wrong as hurricanes aren't the main cause of the dead zone (nutrient pollution is). Option C correctly states that farming (with its runoff) in one region (Midwest) affects ecosystems (Gulf) far away.

Answer:

C. Farming in one region affects ecosystems far away
