Question

A few years after a major oil spill, which area is most fragile in terms of biodiversity?

1 benthic areas
2 polar water
3 middle water
4 open ocean

Answer 1

middle

Step-by-step explanation:

Answer 2

The answer is middle water. After a spill, the oil first affects the open waters where the oil first accumulates. After some years, the oil gets broken down into small particles by oil-eating bacteria and become dissolved in water. They accumulate in the middle oceans and affect biodiversity of this region.
